Plz help me on this I dont understand how to do it. B.) SUBSTITUTION METHOD

1) 2x + 8y = 20 2) x = 5
y = 2 2x + y = 10

Our goal is to fit the given information into the slope-intercept form.
y=mx+b

We can place the slope in 'm.'
y= -7x+b

Then, input the values for the x and y.
2= -7(-5)+b
2=35+b
b=2-35
b= -33

'b' is the intercept, so now that we know that, we can plug in all the values and find our final equation.

y= -7x -33
