Question

what is the equation of the line that passes through the points (−3, 2) and (−5, 8)? 3x − y = −11 3x y = − 7 3x y = 5 x 3y = 3

Answer 1

Gradient, m=
`(change in y)/(change in x)`
m=
`(8-2)/(-5--3)`
m=
`(6)/(-2)`
m=-3
Equation;
y=mx+c
y=-3x+c
Using point (-3,2) to replace for x and y;
2=-3(-3)+c
2=9+c
c=-7
y=-3x-7
