Question

What is the equation of the following line? (1,7) (0,0)

Answer 1

Anytime x = 0 in a point the y intercept is immediately defined.

y = mx + b The y intercept is b

y = 0 + b

0 = 0 + b

b = 0

What you know so for is

y = mx + b

y = mx since b = 0

7 = m*1

m = 7

The answer is y = 7x <<<<<<Answer.
