Question

Complete the equation of the line whose y-intercept is (0, -1) and slope is 4.
y=

Answer 1

y=4x-1

Explanation:

So since we know the slope, we can start with the simple equation: y=4x

Then, we plug in that when x=0, y=-1, with the given point.

So we simply combine the 2 statements to get y=4x-1
