"ou have discovered another alien. find the correct
escue path before answering this question.
which statements are true about the equation of the
ine used to save this alien?
the y-intercept is not visible on the graph
the slope does not exist for this line.
the y-intercept is positive.
the line crosses the x-axis at -3.

Correct options are A and D.

Step-by-step explanation:

From the given graph it is clear that the spaceship is located at (-4,3). The alien is at (-2, -3).

If a line passes through two points and , then the equation of line is

The equation of line is

Add 3 on both sides.

               .... (1)

Slope intercept form of a line is

               .... (2)

where, m is slope and b is y-intercept.

On comparing (1) and (2) we get

It means,

Slope = -3

y-intercept = -9

Points from -6 to 6 are labeled on y-axis. The y-intercept is -9, so it is not visible on the graph. Option A is correct.

Substitute y=0 in equation (1) to find the x-intercept.

Divide both sides by 3.

x-intercept is -3. It means the line crosses the x-axis at -3. Option D is correct.
