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

Question

y= 3x + 1

Answer 1

This equation is in the format of. the standard formula

y=mx+b

where m is defined or known as the slope. The slope is defined as the change of y when divided by the change of x . Also referred as the rise over the run sometimes. The slope measures how steep a line is by comparing its vertical change to its horizontal change.

In the equation shown above, b is the y-intercept which is the value of y when x=0.

slope=3.

y-intercept=b=1. This represents the point (0,1).

Answer 2

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)
