PLEASE HELP ME !!!! I BEG YOU!!!!!

Answer 1

Q3.

`(0;\ 7);\ (5;\ 3).\\The\ slope:m=(3-7)/(5-0)=(-4)/(5)`

Answer:
`y=-(4)/(5)x+7`

Q4.
The horizontal line: y = a

Answer: y = 4

Q5.
x-intecept of Ax + By = C is that value of x for which y = 0

2x + 4y = -10
/subtitute y=0/
2x + 4 · 0 = -10
2x = -10 |divide both sides by 2
x = -5

Answer: (-5; 0)

Q6.
x = a is the vertical line

x = 5

Answer: Graph #4.

Q7.
6x - 4y = -8 |subtract 6x from both sides
-4y = -6x - 8 |divide both sides by (-4)
y = 1.5x + 2
y-intercept (0; 2)

1.5x + 2 = 0 |subtract 2 from both sides
1.5x = -2 |divide both sides by 1.5
x = -1 1/3
x-intercept (-1 1/3; 0)

Answer: Graph #3.
