Question

Find the equation of the line use exact numbers y=

Answer 1

I WILL TAKE THE POINTS (0,7) AND (2,1) FROM THW GRAPH AND USE THEM TO GET THE GRADIENT.

`m (y2 - y1)/(x2 - x1) \\ = (1 - 7)/(2 - 0) \\ m = ( - 6)/(2) \\ m = - 3`

I WILL USE THE POINT (0,7) TO FIND THE VALUE OF C IN THE GENERAL EQUATION.

`7 = - 3(0) + c \\ c = 7`

THE EQUATION IS

`y = - 3x + 7`

ATTACHED IS THE SOLUTION
