Question

What are the x and y intercepts
1) 1500=30x+50y
2)y= -3/4x-3

Answer 1

Explanation:

the x intercepts put y=0

the y intercepts put x=0

Answer 2

Answer: 1) x-intercept = (50, 0) y-intercept = (0, 30)

2) x-intercept = (-4, 0) y-intercept = (0, -3)

Explanation:

The x-intercept is when y = 0

The y-intercept is when x = 0

1) 1500 = 30x + 50y

x-intercept y-intercept

1500 = 30x + 50(0) 1500 = 30(0) + 50y

1500 = 30x 1500 = 50y

50 = x 30 = y

(50, 0) (0, 30)

2)
`y=-(3)/(4)x-3`

x-intercept y-intercept

`y=-(3)/(4)x-3`
`y=-(3)/(4)x-3`

`0=-(3)/(4)x-3`
`y=-(3)/(4)(0)-3`

`3=-(3)/(4)x` y = -3

12 = -3x (0, -3)

-4 = x

(-4, 0)
