Answer:
Explanation:
The slope is Rise over run, aka change in x over change in y (y/x)
Thus, with the coordinates, we can subtract them and find out the slope
x y
-6,-6
-
-3,0
-6-(-3) = -6+3=-3 = change in x
-6 -0 = -6 = change in y
Slope: -6/-3 or 2 (simplify fraction)
Y-intercept can be found by plugin of a random point into the
slope-intercept form equation
y=mx+b y, x, m = slope, and b=y intercept.
Let's choose -3, 0
x=-3 and y= 0
0=2(-3) +b
Now we solve for b
Multiply
0=-6+b
Add 6
b=6
Y-intercept = 6
