Question

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. If Shawn knows that the slope of the line is 4 and the line passes through the point (1,8), which equation should be use to find the y-intercept and what is the y-intercept of the line?

Answer 1

y = 4x + 4

Explanation:

Plug in your x and y coordinates

8 = 4(1) + b

8 = 4 + b get your constants together by subtracting 4 from both sides

4 = b

Hope this helps
