Answer:

Option d is the correct answer

Explanation:

The slope-intercept form of an equation for a line passing through given points can be represented as

y = mx + c

Where

Slope, m = (change in value of y on the vertical axis) / (change in value of x on the horizontal axis)

c = y-intercept

We want to find the slope-intercept form of an equation for the line that passes through (–1, 2) and is parallel to y = 2x – 3

For two lines to be parallel to each other, the slopes must be equal.

For y = 2x – 3

Slope,m = 2 (comparing with the slope intercept form stated above).

This means that the slope of the line

that passes through (–1, 2) is also 2

To find the y-intercept, c of this equation,

2 = 2 × - 1 + c

2 = -2 + c

c = 2+2 = 4

The equation is

y = 2x + 4
