Answer:
y = 5/2x +6
Explanation:
The slope-intercept form of the equation of a line is ...
y = mx +b . . . . line with slope m and y-intercept b
__
The above equation can be solved for b to give ...
b = y -mx
Using the given values m = 5/2 and (x, y) = (-6, -9), we find b to be ...
b = -9 -(5/2)(-6) = -9 +15 = +6
Then the slope-intercept equation is ...
y = 5/2x +6
