Question 1 (Multiple Choice Worth 4 points)

Consider the following system of equations:

y = 5x + 6
y = −x − 7

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

Line y = 5x + 6 intersects line y = −x − 7.
Lines y = 5x + 6 and y = −x − 7 intersect the x-axis.
Lines y = 5x + 6 and y = −x − 7 intersect the y-axis.
Line y = 5x + 6 intersects the origin

Answer 1

Please show me the work you have so far.

Answer 2

ok I have \[5x-5+6-5=x=1\]

Answer 3

how do you solve systems of equations of this form graphically?

Answer 4

I think you Just put them on a graph correct

Answer 5

yes - and what does a point of intersection give you?

Answer 6

the coordinates

Answer 7

the coordinates of the solution to the system
other probabilities are the 2 equations give the same line or they are parallel
- infinite solutions and no solution respectively

Answer 8

* possibilities

Answer 9

if you try to solve this system and get one value for x it will be the first of the 3 types

Answer 10

so if you find that the answer is the first option

Answer 11

As y is equal to both 5x + 6 and -x - 7 we can say

5x + 6 = -x - 7

try solving for x and see what you get

Answer 12

do you need help solving this?

Answer 13

I tried it and got A

Answer 14

yes a is correct option
