Question

What is the equation?

Answer 1

y=-2+4

Explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

`(0-4)/(2-0)`

solving that would come out to be
`(-4)/(2)`

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4
