A line has a slope of 7 and a y-intercept of -4. What is its equation in slope intercept form

The slope-intercept equation for a line:
y = mx + b where m is the slope

Given m = 7, we have:
y = 7x + b

The y-intercept is found by setting x to 0:
y = 7(0) + b
y = 0 + b
y = b

We're given the y-intercept is -4, so we have:
b = -4

So our slope-intercept equation is:
y = 7x - 4
