5x - y = 8

Part A: Explain how you will show all of the solutions that satisfy this equation. (4 points)

Part B: Determine three different solutions for this equation. (4 points)

Part C: Write an equation that can be paired with the given equation in order to form a system of equations that is inconsistent. (2 points)

Answer 1

I'll try to help you :)

Answer 2

TY!

Answer 3

Alright, so for Part A: You can convert it to make it look more like a linear equation. Example: y=mx+b. The number of solutions is infinite because there is no limit to what you can put for x to get y.

Does that make sense?

Answer 4

yes i understand A. i just really need help with B and C

Answer 5

For Part B: You have to plug in three different numbers for x to get y. You have to write all three in this form (x,y). So I THINK it may be this- (3,7)----5(3)-7=8.

Answer 6

For Part C: Inconsistent equations R parallel lines. So from find the slope from A and make up your own with the same slope. (3,7)----5(3)-7=8.



For Part B: (2,4)-----5(2)-4=8 (My mistake! Sorry!)

Answer 7

how did you come up with (2,4)---5(2)-4=8? and (3,7)---5(3)-7=8?

Answer 8

im a little slow, i know :/

Answer 9

5x - y = 8

just sub any number in for x and find y.

make x = 1
5(1) - y = 8
5 - y = 8
5 - 8 = y
- 3 = y
so when x = 1, y = -3

now pick another number to plug on for x
x = 2
5(2) - y = 8
10 - y = 8
10 - 8 = y
2 = y
so when x = 2, then y = 2

now you can pick a number for x and solve for y
understand ?

Answer 10

as for C....for them to be inconsistent, they cannot intersect...they are parallel.
Parallel lines will have the same slope, but different y intercepts.

Answer 11

x=3
5(3)-y=8
15-y=8
15-8=y
y=7
x=3,y=7 (:

Answer 12

how can i make them not intersect?

Answer 13

x = 3, y = 7 ....correct

Answer 14

parallel lines will have same slope and different y intercepts
