Please help me out math test!?

1.explain whether the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) represent the set of all the solutions for the equation y=−5x−7.

2.Select the two correct answers.

(1 point)

The y-intercept is −4.

The slope is 12.

The slope is −2.

The x-intercept is 4.

The y-intercept is 12.

    1. y=−5x−7.is the equation for a line whose domain is (-∞,+∞) and range is (-∞,+∞).

    Therefore, the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) IS NOT the set of all the solutions for y = -5x - 7. ..............ANS

    -------------------------

    2. Out of the 4 possible choices describing the graph,

        there is ONLY 1 CORRECT ANSWER:

       

                 y-intercept is −4  ...................ANS

    That the equation of a line that has an infinite number of points in the solution set. That set only contains 5 of the infinitely many points on the line so it isn't complete.

    The second line has an x-intercept of 8, a y-intercept of -4 and a slope of ½

    Only *one* of the statements is accurate (unless the slope of 12 was supposed to be 1/2).
