Which equation is the slope formula?
Choice 1.) ax + by = c
Choice 2.) y-y1=m(x-x1)
Choice 3.) y = mx + b
Choice 4.) m = y2-y1
x2-x1
Choice 4.) m = y2-y1
x2-x1
What is the y-intercept of this line?
y = 7x -12

Get y by itself.
8x + 4y = 16
8x + 4y = 16
4y = -8x + 16
y = -2x + 4
Which of the following equations shows a HORIZONTAL LINE when it is graphed?
1.) y = 10
2.) x = 12
3.) y= 2x + 3
1.) y = 10
Using these points, write a linear equation.
(8,2)(10, 7)
HINT: Find the slope, then the y-intercept, then rewrite.
(8,2)(10, 7)
Slope = 5/2 or 2.5
y = 2.5x + b
7 = 2.5(10) + b
7 = 25 + b
b = -18
y = 2.5x - 18
Which equation is standard form?
Choice 1.) ax + by = c
Choice 2.) y-y1=m(x-x1)
Choice 3.) y = mx + b
Choice 4.) m = y2-y1
x2-x1
Choice 1.) ax + by = c

3.) Mrs. Brault
2.) Mrs. Nadge
Get this equation in slope intercept form:
5y = 10x - 20
5y = 10x - 20
y = 2x - 4

Find the slope using the following points:
(9, -2) (6, 5)
m = -7/3
Write this equation in y = mx + b form.
-7 - y = 11x
-7 - y = 11x
-y = 11x + 7
y = -11x -7
