Question

Plz help me I don’t understand

Answer 1

Explanation:

Take two points on the line and find the slope.

(1 , 2) ; (4 , 4)

Slope =
`(y_(2)-y_(1))/(x_(2)-x_(1))\\\\`

`=(4-2)/(4-1)\\\\=(2)/(3)`

m = 2/3 & (1 , 2)

Slope point form : y - y1 = m(x-x1)

`y - 2 = (2)/(3)*(x - 1)\\\\y - 2 =(2)/(3)x - (2)/(3)\\\\y =(2)/(3)x-(2)/(3)+2\\\\y = (2)/(3)x-(2)/(3)+(2*3)/(1*3)\\\\y=(2)/(3)x-(2)/(3)+(6)/(3)\\\\y=(2)/(3)x+(4)/(3)\\\\Multiply \ equation \ by \ 3\\\\3y = 2x + 4\\\\2x - 3y + 4 = 0`
