Question

Find where the lines y =-3x + 2 and y = 5x 6 cross in the coordinate plane.

Answer 1

(1, -1)

Explanation:

Given lines

• y = -3x + 2
• y = 5x - 6

They cross at:

• -3x + 2 = 5x - 6
• 5x + 3x = 2 + 6
• 8x = 8
• x = 1

The y coordinate is:

• y = -3*1 + 2 = -1

So the lines cross at point (1, -1)
