Question

y = 5x + 6
y = −x − 7

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

Answer 1

Use the substitution method
E1 tells you what y equals
5x+6=-x-7
Solve for x

Answer 2

I got x = -13/6 but I'm still unsure of what the answers mean.
A.Line y = 5x + 6 intersects line y = −x − 7.
B.Lines y = 5x + 6 and y = −x − 7 intersect the x-axis.
C.Lines y = 5x + 6 and y = −x − 7 intersect the y-axis.
D.Line y = 5x + 6 intersects the origin.

Answer 3

@jim_thompson5910 can you help? Please? After seeing the answer choices i confused..

Answer 4

*im

Answer 5

solve `5x+6=-x-7` for x to get

5x+6=-x-7
5x+6+x=-x-7+x
6x+6 = -7
6x+6-6= -7-6
6x = -13
6x/6 = -13/6
x = -13/6

so I agree with you @lilly249
I'm getting the same x value

Answer 6

now plug x = -13/6 into either equation to find y


y = 5x+6
y = 5(-13/6)+6
y = -65/6+6
y = -65/6+6*(6/6)
y = -65/6+36/6
y = (-65+36)/6
y = -29/6

Answer 7

the two lines cross at (-13/6, -29/6)

this point is NOT on the x axis
this point is NOT on the y axis
this point is in quadrant Q3

Answer 8

Choice B,C,D are wrong because of what I said in my last post

Answer 9

How is it not in the x and y- axis? I'm confused, I'm sorry T_T

Answer 10

if it were on the x axis, then the y coordinate would be 0
if it were on the y axis, then the x coordinate would be 0
if it were on the origin, then both x and y coordinates would be 0

Answer 11

OHHHHHH ok thanks!!

Answer 12

no problem
