Question

Find the coordinates of the point of intersection for eaach of the pair of lines: y=-4x and y=-x+10

Answer 1

( -10/3 , 40/3 )

Explanation:

→ Equate both lines

-4x = -x + 10

→ Add x to both sides

-3x = 10

→ Divide both sides by -3

x = -10/3

→ Substitute into y = -4x to find y

y = 40/3
