URGENT HELP PLEASE
sammy [17]

Answer:

slope1 : 7,  slope 2 = 3     solution: (2,5)

Step-by-step explanation:

I simplify some steps

pair 1:    x1   0     2

            y1   -9     5 ........ -9, y1 intercept

pair 2:   x2   0    2

             y2  -1    5   ........ -1, y2 interept

2 pairs meet at (2,5)

y=7x-9 ......A

y=3x-1  ......B

A-B    0=4x-8

4x=8

x=2

y=5

slope 1=( y2-y1) / (x2-x1) = (5- -9)/(2-0) = 14/2 =7

slope 2 = (5 - -1) / (2 - 0) = 6/2 = 3
