Question

What points do y = -2x + 7 and y = 5x - 14 intercept on a graph

Answer 1

Answer:

(3, 1)

Explanation:

because that's where they intercept

Answer 2

Answer:

Both lines intersects at (3, 1)

given:

• y = -2x + 7

• y = 5x - 14

solve them simultaneously:

• -2x + 7 = 5x - 14

• 5x + 2x = + 7 + 14

• 7x = 21

• x = 3

solve for y:

• y = -2x + 7

• y = -2(3) + 7

• y = -6 + 7

• y = 1
