How to solve:
Find the slope-intercept (y = mx + b) equation of the line with a slope of 4 passing through (3, 17).
y = mx + b.
Substitute 4 (the slope) in for m:
y = 4x + b
To find b, substitute 3 for x and 17 for y:
17 = 4(3) + b.
Solve for b:Click
to see how.
b = 5.
y = 4x + 5.
Here's one to try:
