Y(0.75 + 7
y(0.75 + 7) =
Please help me quick

Slope = 1.500/2.000 = 0.750

 x-intercept = 21/-3 = 7/-1 = -7.00000

 y-intercept = 21/4 = 5.25000

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
