Question

What is the answer???

Answer 1

3.
`\displaystyle x-intercept: [-4(1)/(2), 0] \\ y-intercept: [0, -9] \\ Slope-Intercept\:Form: y = -2x - 9`

2.
`\displaystyle x-intercept: [5, 0] \\ y-intercept: [0, 1] \\ Slope-Intercept\:Form: y = -(1)/(5)x + 1`

1.
`\displaystyle x-intercept: [4, 0] \\ y-intercept: [0, -3] \\ Slope-Intercept\:Form: y = (3)/(4)x - 3`

Explanation:

−2x - y = 9

x-intercept → Plug in 0 for y to get −4½ for x

y-intercept → Plug in 0 for x to get −9 for y

−2x - y = 9

+ 2x + 2x

_________

`\displaystyle (-y)/(-1) = (2x + 9)/(-1)`

`\displaystyle y = -2x - 9 →`Slope-Intercept Form

_______________________________________________

x + 5y = 5

x-intercept → Plug in 0 for y to get 5 for x

y-intercept → Plug in 0 for x to get 1 for y

x + 5y = 5

- x - x

_________

`\displaystyle (5y)/(5) = (-x + 5)/(5)`

`\displaystyle y = -(1)/(5)x + 1 →`Slope-Intercept Form

_______________________________________________

3x - 4y = 12

x-intercept → Plug in 0 for y to get 4 for x

y-intercept → Plug in 0 for x to get −3 for y

3x - 4y = 12

- 3x - 3x

_________

`\displaystyle (-4y)/(-4) = (-3x + 12)/(-4)`

`\displaystyle y = (3)/(4)x - 3 →`Slope-Intercept Form
