Accepted Solution

A:

1. 2x + 3y = 16....just a matter of subbing...answer is (5,2) <=

2. to find the x int, sub in 0 for y and solve for x

-2x + 5(0) = -20

x = -20/-2

x = 10......or (10,0) <=

3. (2,-5)(4,1)...using slope formula : (y2 - y1) / (x2 - x1)

slope = (1 - (-5) / (4 - 2) = 6/2 = 3 <=

4. y = 4x - 3....the first 3 are true
