Question

Please help explanation if possible

Answer 1

Answer:

y=-3x+5

Step-by-step explanation:

concepts: y=mx+b is slope intercept equation formula

m=slope

b= y intercept

Therefore we need to find the slope and y intercept

first find slope

m=$\frac{y2-y1}{x2-x1}$

let y2 be 2

let y1 be -4

let x2 be 1

let x1 be 3

$\frac{2-(--4)}{1-3}$

6/-2 = -3

m=-3

slope is -3

y= -3x+ b

we need find y intercept now

just plug in (1,2) into that equation

2=-3(1)+b

b=5

y=-3x+5
