Notice that in the chart, the 2 grey sections slope and y-intercept are the two numbers that we need in order to write our equation. We also now know the y-intercept bwhich is 9 because we just solved for b.

These two numbers are related. Although you have the slope, you need the y-intercept. Now you are ready to solve real world problems given two points. We also now know the y-intercept bwhich is 3 because we just solved for b.

Then we can write our equation. We know the slope and a point x,y. This relation means that we know the x and y coordinates of an ordered pair.

You have enough information to find the y-intercept, but it requires a few more steps. Writing Linear Equations Given Slope and a Point When you are given a real world problem that must be solved, you could be given numerous aspects of the equation. Now we know the slope m is 1.

We can use this information to solve for b. You have all the information you need, and you can create your graph or write an equation in slope intercept form very easily. You must always know the slope m and the y-intercept b. Now we know the slope m is -2 because that was given to us. Writing Equations Given Slope and a Point Write the equation of a line, in slope intercept form, that passes through the point 6, -3 with a slope of Write a linear equation that can be used to determine the cost of a cab ride to anywhere around Washington DC.

We can now write our equation! I know that this is a rate and therefore, is also the slope. It could be slope and the y-intercept, but it could also be slope and one point or it could be just two points. The slope is going to be your "rate" and the point will be two numbers that are related in some way.

Once you have m slope and b y-interceptyou can write an equation in slope intercept form. Here you will have to read the problem and figure out the slope and the point that is given. If you are given slope and a point, then it becomes a little trickier to write an equation.

If you are given slope and the y-intercept, then you have it made.

Then you will solve for b.I CAN write an equation in slope intercept form and graph the line using slope intercept form. HW: Worksheet Yes No Section I CAN write an equation in slope intercept form given the slope and a point on the line. HW: Worksheet Yes No Section I CAN write an equation in slope intercept form given two points on.

Write the slope-intercept form of the equation of each line. 1) 3 x − 2y = −16 2) Write the point-slope form of the equation of the line described.

17) through: (4, 2), parallel to Writing Linear Equations Date_____ Period____ Write the slope-intercept form of the equation of each line.

Writing Equations of Lines Review for Quiz Period____ A. Write the slope-intercept form of the equation of each line given the slope and y-intercept.

1) Slope = 5, y-intercept. If the slope of a line is undefined and line goes through the point (-3, ), express the equation of this line in slope-intercept form.

Show Answer Since the slope is undefined, the line is a vertical line. Practice for slope, y-intertcept, and writing equations Write the slope-intercept form of the equation of each line given the slope and y-intercept. 1) Slope = −1, y-intercept = −5 2) Slope = −1, y-intercept = −1.

Write the point-slope form of the equation of the line through the given points. 17) through: (,) and (,) 18) through: (,) and (,) Write the slope-intercept form of the equation of the line through the given point with the given slope.
