identify the slope and y-intercept in y=3x+1

Question

y= 3x + 1

Answer 1

Hi Sabrina;

The equation is in the format of...

y=mx+b

m is the slope, the change-of-y divided by the change-of-x, also known as rise-over-run.

b is the y-intercept, the value of y when x=0.

slope=m=3

y-intercept=b=1, corresponding to point (0,1)
