Question

What is the equation of the line shown in this graph

Answer 1

y = -2x+4

Explanation:

points (1,2) (4,-4)

slope = (y2-y1)/(x2-x1)

= (-4-2)/(4-1)

= -6/3

= -2

point slope form

y-y1= m(x-x1)

y-2 = -2(x-1)

to change to slope intercept form

distribute

y-2 = -2x+2

add 2 to each side

y = -2x+4
