Answer:

Step-by-step explanation:
The formula of a slope:

If
m > 0, then a line is rising
m < 0, then a line is falling
m = 0, then a line is horizontal
m is undefined, then a line is vertical
<h2>a.</h2>
(2, 1) and (4, 5)

<h2>b.</h2>
(-1, 0) and (3, -5)

<h2>c.</h2>
(2, 1) and (-3, 1)

<h2>d.</h2>
(-1, 2) and (-1, -5)

A slope of any line parallel to y = x + 2 will be 1.
The slope of parallel lines are always equal. Since we do not see a number next to the x in the original equation, there is an assumed 1 there. Therefore any line that is parallel with it would also have to be 1.
