Question

13 and 15solve each problem by graphing and slope intercept​

Answer 1

Answer: The answers are 13. (A) and 14. (B).

Step-by-step explanation: The calculations are as follows:

(13) The given equations are

$y=-\dfrac{3}{8}x-6,\\\\\\y=-\dfrac{13}{8}x+4.$

In the attached figure (a), these two lines are drawn. We can see that The lines intersect at the point P(8, -9). So, the solution to the pair of equations is (8, -9).

Thus, the correct option is (A).

(14) The given equations are

$y=-\dfrac{1}{7}x-1,\\\\\\y=-x+5.$

In the attached figure (b), these two lines are drawn. We can see that The lines intersect at the point Q(7, -2). So, the solution to the pair of equations is (7, -2).

Thus, the correct option is (B).
