Question

Which description best describes the solution to the following system of equations?

y = −one halfx + 9
y = x + 7

Lines y = −one halfx + 9 and y = x + 7 intersect the x-axis.
Lines y = −one halfx + 9 and y = x + 7 intersect the y-axis.
Line y = −one halfx + 9 intersects the origin.
Line y = −one halfx + 9 intersects line y = x + 7.

Answer 1

geez - ever think of using actual numbers, like oh, say -- 1/2 ??

since neither line is horizontal or vertical, and their slopes are different, all of the statements are true except the third one.

However, only the fourth one has anything to do with the solution -- that is, where they intersect.

Answer 2
