Question

Can I get help with 15. Please help me and show work

Answer 1

`y=2x+1`

Step-by-step explanation (Using Slope Intercept Form) :

The line crosses at 1, so 1 is the y-intercept.

The slope of the line is 2.

I picked (1,3) and (0,1) as my points.

`m=(rise)/(run)=(y2-y1)/(x2-x1) =(3-1)/(0-1) = (2)/(-1)`

However due to the line going in a positive direction, the slope is positive.

In slope intercept form, m is the slope and b is the y intercept.

`y=mx+b\\y=2x+1`
