Answer:
y = (3/4)x - 9
Step-by-step explanation:
The slope-intercept form of the equation of a straight line is y = mx + b.
Here we know x, y and m, but must find b.
Substituting 8 for x, -3 for y and 3/4 for m in the equation above results in:
-3 = (3/4)(8) + b, or (after multiplying all three terms by 4 to clear fractions):
-3 = 6 + b
Then b = -9, and the desired equation is y = (3/4)x - 9
