Question

Select the equation of the line that passes through the point (3, -1) and is parallel to the line on the graph.

y = -1

y = 3

y = x -1

y = 3x - 1

Answer 1

I'm not sure which graph you are speaking of but the one I see has 0 slope.
Parallel to the 0-slope: m=0 line graphed in your attachment?

Line parallel to 0 slope will have 0 slope, and passes through y = -1, x = 3 will give:

y=mx+b form yields -1=0(3)+b
b=-1
m=0

It is not possible for a line with 0 slope with y-intercept at -1 to pass through x=3

Answer 2

Exactly

Answer 3

The line y = 3x - 1 has a slope of three,

-1 = 3(3) - 1, plugging in the point yields -1 = 8, which is false. There is no solution.

Answer 4

Ok, thanks for trying anyways

Answer 5

The line in the graph has a slope of zero, passing through (0,2.5).

A line parallel to "the line in the graph" has the general form:
y=b where b is a constant.
x does not appear in the equation.
The point that the line needs to pass through is (3, -1)
Can you find the choice with the help of the diagram below?
