Question

Find the slope for these equations y=-5(2x-3) 10y+6x=-90 12y -4x=-24

Answer 1

1. y = -5 (2x - 3)  x-intercept =   (3/2 , 0)         1.  0 = -5 (2 * 3/2 - 3)
                           y-intercept=    (0 , 15)

2. 10y + 6x = -90    x-intercept=   (-15 , 0)
                               y-intercept=   (0 , -9)         2. 10 * 0 + 6 * -15 = -90

3. 12y - 4x = -24     x-intercept=   (6 , 0)
                               y-intercept=   (0 , -2)         3. 12 * 0 - 4 * 6 = -24
 
slope 1. -10

slope 2. -3/5

slope 3.  1/3

Answer 2

1) 2x 2) 6x 3) -4 There you go
