Answer:
y = 10x - 31
Step-by-step explanation:
The general form for a linear equation in slope-intercept form is
y = mx + b where m is the slope and b is the y-intercept
Use what we know about our line to solve the rest. By using one of the given points, we have 3 of the 4 variables in the above equation. We use (4, 9), which is (x, y), and we know that
m = 10
The equation becomes...
9 = 10(4) + b (now solve for b)
9 = 40 + b
-31 = b
Plug that value into the general form...
y = 10x - 31
