EDGE Math 8

Determine the intercepts of each given line. Let a = x-intercept and b = y-intecept. Choose the correct answer.

1.	$2 x + 3 y = 12$

a = - 4

and

b = 6

a = 6

and

b = 4

a = 4

and

b = 6

none of the choices

Answer: $a = 6$ and $b = 4$

2.	$y = \frac{5}{6} x - 10$

a = 12

and

b = - 10

a = 10

and

b = 12

a = - 10

and

b = 12

none of the choices

Answer: $a = 12$ and $b = - 10$

3.	$\frac{x}{8} + \frac{y}{2} = - 1$

a = 8

and

b = 2

a = - 2

and

b = - 8

a = - 8

and

b = - 2

none of the choices

Answer: $a = - 8$ and $b = - 2$

4.	$7 x - 35 = 0$

a = 5

and no y-intercept

b = 5

and no x-intercept

a = 0

and

a = 5

none of the choices

Answer: $a = 5$ and and no y-intercept

5.	$100 y + 25 = 0$

b = \frac{1}{4}

and no x-intercept

b = 4

and no x-intercept

b = - 4

and no x-intercept

none of the choices

Answer: none of the choices; $b = - \frac{1}{4}$ and no x-intercept
