Question

Write an equation for the line graphed below: y=??

Answer 1

Answer: y=-2x-1

Step-by-step explanation:

First let's find the slope by using the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$\frac{-3--1}{1-0} \\\frac{-2}{1} \\-2$

The equation for slope intercept form is y=mx+b where m is the slope and b is the y-intercept

The y-intercept is -1 giving us the equation

y=-2x-1
