Question

Hello please help if you can

Answer 1

C) y = 2x +8

Equation of the straight line passing through the point (-2,4) and having slope m =2

y = 2x +8

Explanation:

Step(i):-

Given that the points are (-2,4) and (6,20)

The slope of the line

m =
`(20-4)/(6-(-2)) = (16)/(8) =2`

m =2

Step(ii):-

Equation of the straight line passing through the point (-2,4) and having slope m =2

y - 4 = 2( x-(-2))

y = 4 + 2x +4

y = 2x +8
