Question

What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−3, 1)?

Answer 1

Answer: The answer is (D)
`y-1=(3)/(2)(x+3).`

Step-by-step explanation: We are given to find the equation of a line which is parallel to the line in the graph and passing through the point (-3, 1).

The points (-2, -4) and (2, 2) lie on the line in the graph, so its slope will be

`m=(2+4)/(2+2)=(6)/(4)=(3)/(2).`

The slope of the line parallel to the line in the graph will also be same. Since the new line passes through the point (-3, 1), so the equation of the line will be

`y=1=m(x+3)\\\\\Rightarrow y-1=(3)/(2)(x+3),`

which is in the slope-intercept form.

Thus, the correct option is (D).
