Add the x to both sides and it turns into Y = x + 4. If this isn't what you're looking for, please provide the answer choices.
It increases the mean value of the prizes.
4x + 15 = 6x - 1
x = 8
m∠JLC = 47°
For y=4 draw a horizontal line through the y-axis at point (0,4). Y-axis is the vertical.
For x=-3 draw a vertical line through the x-axis at point (-3,0). X-axis is the horizontal.
