Question

What is the equation of the line shown in the graph, in standard form ? please help me as soon as possible.

Answer 1

First find two points and locate its coordinate

(-2, 0) and (-3, -2)

x₁=-2

y₁=0

x₂=-3

y₂=-2

substitute the values into the formula below

`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)`
`y-0=(-2-0)/(-3+2)(x+2)`

`y=(-2)/(-1)(x+2)`

`y=2(x+2)`

y= 2x + 4

Re-arrange

2x - y = -4
