Answer:
y=12x-4
Step-by-step explanation:
To find the slope intercept form, we know the m(slope) but we need to find b.
y and x is given to us, so we can find b.
Plug in the numbers provided into the slope intercept form.
y=mx+b
20=(12)(2)+b
20=24+b
To find b, we have to get b by itself. So, we subtract both sides by 24.
-4=b
Now that we found b, we can plug this into the equation.
y=12x-4
