Slope intercept form line equation is y = mx + b, m is slope and b is y-intercept.
Y-intercept is -4.
X-intercept is the line crosses the x-axis so, y = 0
0 = -4x + 16
subtract 16 from each side
-16 = -4x
divide each side by -4
x = 4
x-intercept is 4.
y-intercept is -4.

Slope-intercept form line equation is y = mx + b, where m is slope and b is y-intercept.

The equation is y = - 4x + 16.

Compare the line with slope - intercept form.

y - intercept is 16.
