Answer: y = -2x + 4
Step-by-step explanation: In slope-intercept form or y = mx + b form,
the y is isolated or by itself on the left side of the equation.
So start by subtracting 4x from both sides.
That gives us -2y = 4x - 8.
Notice I put the x term first because in y = mx + b form,
the x term comes first on the left side of the equation.
From here, we divide both sides by -2 to get y = -2x + 4.
