Question

Complete the equation of the line through (-8, 8,) and (1, -10)

Answer 1

Answer:

Equation of a line has form of y = ax + b

This line passes (-8, 8) and (1, 10), then:

-8 = -8 x a + b

10 = a + b

Subtract 2nd equation to 1st equation, then:

18 = 9 x a

=> a = 2

=> b = 10 - 2 = 8

=> y = 2x + 8

Hope this helps!
