Answer:
Step-by-step explanation: You first take 10 away form the left side of the equation, subtracting it from the right.
Then you add y to the left and get rid of it on the right you now have y = -5/2x -10. Because the slope is -5/2 you go up 5 over 2 and the y intercept is -10 by that reasoning the x intercept is -4
