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

y = -1

Explanation:

The graphed function is:

• y = 2.5

The line parallel to this has to be in the form of:

• y = k, where k≠ 2.5

Since the line passes through the point (3, -1), its y coordinate is -1, therefore the function is:

• y = -1

Correct option is the first one
