Answer:
The slope is 4, and the y-intercept is 12.
Step-by-step explanation:
[tex]\text{A slope}\ m=\dfrac{rise}{run}=\dfrac{\Delta y}{\Delta x}\\\\\text{Look at the picture.}\\\\m=\dfrac{-4}{-1}=4[/tex]
[tex]\text{an y-intercept:}\\\text{Look at the second picture}\\\\for\ x=-2\to y=4\\for\ x=-1\to y=4+4=8\\for\ x=0\to y=8+4=12\\\\y-intercept=12[/tex]
