You always want to get y by itself and in the form y = mx + b. So first, subtract 4x from both sides to get -y = -4x +32 You also want to get rid of that negative sign. That’s easy, divide everything by negative 1 to get: y = 4x - 32
We can see the slope is just 4 and the y intercept is -32. The y-intercept is when x equals zero, you’ll get -32 if you do so. The x-intercept is now when y equals zero. Now solve for x. You get 4x = 32, divide by 4 to get 8
