Question

1. what is the solution of the system y=10x-3 y=7x+2

2. what is the slope of the line that passes through the pair of points (-2,70 (18,1)

Answer 1

A

Explanation:

Answer 2

1. [5/3, 41/3]

2. -3.45

Explanation:

1. Y =10x - 3, Y = 7x + 2

Therfore, 10x - 3 = 7x + 2

X = 5/3

So, Y = 50/3 - 3

= 41/3

2.y2-y1/x2-x1 = m

1 - 70/18-(-2)

= -69/20

= -3.45
