Question

What is the slope-intercept equation for the line below?

Answer 1

the answer is y=-3x+4 becasue the y intercept is 4 and it goes down 3 for every 1 to the right.

Answer 2

y=-3x+4

Explanation:

To find the equation of the given line we use y=mx+b

where m is the slope and b is the y intercept

y intercept is the point wher the line crosses y axis

The graph crosses y axis at 4 so b= 4

Now we find slope using formula
`(y2-y1)/(x2-x1)`

To find slope pick two points from the graph

(0,4) and (1,1)

slope =
`(1-4)/(1-0)=-3`

slope m = -3

So equation of the line y=mx+b is y=-3x+4
