Question

How many solutions does the system y = -7x + 3 and y + 7x = 10 have? Explain.

A. No solutions; the lines are parallel.
B. One solution; (0, -7)
C. Infinitely many solutions; the lines are the same.
D. No solutions; the lines are perpendicular.

Answer 1

Explanation:

y = -7x + 3

y + 7x = 10 or y= -7x+ 10

no solution, because the b's are different but the rest of the function is the same
