Question

What is the equation of the line whose Y intercept is 3 and slope is 1?

A) Y=x-3
B) Y=x+3
C) Y=3x+1

Answer 1

Y=Mx+b m=slope b=y-intercept thus Y=1x+3 and you can drop the one so the answer is b)y=x+3

Answer 2

y=x+3

Explanation

The slope intercept form equation is y=mx+b. m is the slope and b is the y intercept. In this scenario, plug it back in to m and b. m=1 and b=3 so it would be y=1x+3. However, we don't include the one so it would just be y=x+3
