Question

What is the equation of a vertical line passing through the point (–5, –1)?

y = –5
y = –1
x = –5
x = –1

Answer 1

x = -5

Answer 2

any vertical line means x = __

Answer 3

y varies directly as the square of x. When x = 3, y = 54. Find y when x = 8.

Answer 4

y = 6x^2

Answer 5

y = 96

y = 144

y = 256

y = 384

Answer 6

y = 6*64 = 384

Answer 7

What is the equation in point-slope form of the line passing through (–2, 0) and (2, 8)?

Answer 8

y = 2(x + 2)

y = 2(x – 2)

y = –2(x – 2)

y = –2(x + 2)

Answer 9

Slope:
(8-0)/(2+2) = 2

Answer 10

y - 0 = 2(x-(-2))
y = 2(x+2)

Answer 11

What is the equation of the line passing through (–3, 6) and parallel to the line y = 4x – 2 in standard form?

Answer 12

x – 4y = –18

x + 4y = 18

4x – y = –18

4x + y = 18
