Answer:
y = -3x - 1
Step-by-step explanation:
1) Find the slope of the line
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{2-(-1)}{-1-0}[/tex]
Slope is -3
2) Plug the slope into a y-intercept form.
y = mx +b
y = -3x + b
3) Find b (which is the y-intercept) by plugging in any coordinates for the x and y.
y = -3x + b
I would like to plug in (0, -1) into the equation.
(-1) = -3(0) + b
-1 = b
4) Plug in the b into the equation.
y = -3x +b
y = -3x -1
