Question

Please help me i need a big help it is very cunfuseing

Answer 1

the answer is C.

Explanation:

Put both equations in the slope intercept form of the line and then graph to estimate where the lines cross.

y = mx + b

7x - y = 7 The 7x is on the wrong side of the equal sign, so subtract 7x from both sides of the equation

7x - 7x -y = -7x + 7

-y = -7x + 7 We want the equation to start y = , not -y =. so divide all the way through by -1

`(-1y)/(-1)` =
`(-7x)/(-1)` +
`(7)/(-1)`

y = 7x - 7

x + 2y = 6 The x is on the wrong side of the equal sign. Subtract x from both sides

x -x + 2y = -x + 6

2y = -x + 6 Divide all the way through by 2

`(2y)/(2)` =
`(-1)/(2)`x +
`(6)/(2)`

y =
`(-1)/(2)` x + 3

You can see from the graph attached where the lines cross.
