Match the correct y=mx+b equation to the graph: <br><br> pls show work/explanation!
Basile [38]

Answer:

y=-3x+2

\boxed{m=-3,\ b=2}

Step-by-step explanation:

<u>Equation of a line</u>

To define the equation of a line, we only need two points through which it passes. The graph shows two clear points to choose: (0,2) and (1,-1)

Set up the equation of the line by using the formula

\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

\displaystyle y-2=\frac{-1-2}{1-0}(x-0)

Operating

y-2=-3x

Rearranging

y=-3x+2

\boxed{m=-3,\ b=2}
