Answer 1

y = 1/4x -4

Explanation:

The line crosses the y-axis at y = -4. That is the y-intercept. (b=4)

The line goes up 1 unit for each 4 units to the right, so its slope is ...

m = rise/run = 1/4

The slope-intercept equation is ...

y = mx +b . . . . . line with slope m and y-intercept b

y = 1/4x -4
