What is the slope-intercept form of the function that contains the point (–1, 5) and has a slope of –4?
1 answer:
If it has a slope of -4, you need to find b.
So you want to plug in your coordinate values for x and y to solve.
5=-4(-1)+b
5=4+b you then subtract 4 from both sides to find the answer for b.
1=b
So your equation would be:
y=-4x+1
