Question

HELP FAST! Which equation is shown on the graph?

A. y = x – 2

B. y = x + 2

C. y = 2x + 2

D. y = 2x

Answer 1

The equation shown on the graph is y = x + 2.

The slope of the line is 1 and the y-intercept is 2.

Hope this helps :)

Answer 2

B. y = x + 2

Explanation:

By the given graph,

The line is passes through the points (-2, 0) and (0, 2),

Since, the equation of a line passes through
`(x_1, y_1)` and
`(x_2, y_2)` is,

`y-y_1=(x_2-x_1)/(y_2-y_1)(x-x_1)`

Hence, the equation of the line shown in the graph,

`y-0=(0+2)/(2-0)(x+2)`

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

`y=x+2`

Therefore, Option 'B' is correct.
