Question

Complete the equation of the line whose y intercept is (0, 6) and the slope is 3

Answer 1

y=3x+6

Explanation:

The slope form can be written as y=mx+b

m is the slope, which is 3 in this case.

b is the y-intercept (6).

Add those values into the slope form equation. Just leave y as is.

Answer 2

It’s y=3x+6 because if you solve for the y-intercept by doing 6=3(0)+b you’ll get b=6. Then you just plug in the m values and the b and you’ll get y=3x+6
