I don't understand how to do these at all. Ive tried for the last hour.

Step-by-step explanation:

I'll help you out

For #4:

4 Parallel means that the lines have the same slope, but different intercept

I'm going to assume it's 2y - 5x = 10

the slope is 5/2

We're given that it goes through the point (-10, 9),

we can substitute with the y = mx + b equation

5 Perpendicular means that the slope of the line is the negative reciprocal of the other line

The first line is y = 5, if you look at this on a graph, it's a straight horizontal line. it's slope is 0.

1/0 is undefined, it'd be a straight line upwards, which can be represented by x = (something)

we're given that it goes through (-2, 9)

so the line is

6

again, parallel = same slope

7

The two points are (0, 4) and (1, 7)

8

the two points are (0, -3) and (3, -1)

9

This is a straight up line, like in problem 5

it is x = -5

the perpendicular line is a horizontal line y = (something)

since it goes through 3 at -3, it is

10

the line is y = 4

a parallel line to this is another horizontal line y = (something)

since it goes through 8, the line is
