Question

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

Answer 1

Answer:

$y=2x+1$

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.

$m=\frac{rise}{run}=\frac{y2-y1}{x2-x1} =\frac{3-1}{0-1} = \frac{2}{-1}$

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.

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