Which description best describes the solution to the following system of equations? (4 points) y = −one-half. gifx + 9
y = x + 7

a
Lines y = −one-half. gifx + 9 and y = x + 7 intersect the x-axis.

b
Lines y = −one-half. gifx + 9 and y = x + 7 intersect the y-axis.

c
Line y = −one-half. gifx + 9 intersects the origin.

d
Line y = −one-half. gifx + 9 intersects line y = x + 7.

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

this cant be answered without the graph. you may need to add it.
