1. ### Math problem help!!!!!!!!!!?

... into the equation. 9. y - 2 = 7(x - 1) y - 2 = 7x - 7 y + 5 = 7x 7x - y = 5 10. Do the same thing. y + 1 = -(x - 3) y + 1 = -x + 3 y = -x + 2 x + y = 2 PS Standard form...

2. ### how would you do this problem? Through ( -2,-2) , parallel to -x +2y = 10?

Through ( -2,-2) , parallel to -x +2y = 10? – x + 2y = 10 2y = x + 10 y = (1/2)x + 10 m = (1/2) Through ( –2, –2) (y + 2) = (1/2)(x + 2) y + 2 = (1/2)x + 1 y = (1/2)x – 1...

9. ### the vertex is (5,2) and it passes through the point (1,10)?

Assuming "it" refers to a parabola. y = a(x - 5)^2 + 2 Substitute (1, 10) for (x, y) and solve for a. 10 = a(1 - 5)^2 + 2 10 = 16a + 2 8 = 16a a = 1/2 y = (x - 5)^2/2 + 2
