Algebra help, please.. any type of help you can with this!?

Question

1.Write an equation of the line with the given slope and containing the given point. Write the equation in the form

Slope 3; through (-3, 4)

a y = 3x - 13

b y = 3x + 13

c y - 4 = x + 3

d y - 4 = mx + 3

Question 2

Find an equation of the line. Write the equation in standard form.

Through (4, 8); parallel to y = 9

a x = 4

b y = 4

c y = 8

d x = 8

Question 3

Find an equation of the line. Write the equation using function notation.

Through (-4, -1); perpendicular to f(x) = 2x - 4

a f(x) = -2x - 3

b f(x) = 2x - 3

c f(x) = x - 3

d f(x) = - x - 3

Question 4

Find an equation of the line. Write the equation in standard form.

Slope - ; y-intercept (0, 4)

a 3x + 11y = 12

b 11x + 3y = 12

c 3x - 11y = 12

d -11x + 3y = 12

Question 5

Find an equation of the line. Write the equation using function notation.

Through (9, 64) and (7, 52)

a f(x) = -6x + 118

b f(x) = 6x + 10

c f(x) = x +

d y = 6x + 10

(no six:p)

Question 7

Determine whether the lines are parallel, perpendicular, or neither.

f(x) = 2x + 9

g(x) = -2x - 9

a parallel

b perpendicular

c neither

Question 8

Find the slope and the y-intercept of the line.

x + 4 = 0

a m = 0; b = 4

b m = 0; b = -4

c m = 4; b = 0

d slope is undefined; no y-intercept

Question 9

Find the slope of the line.

4y - 2x = -16

a - 1/2

b - 2

c - 4

d 1/2

Question 10

Find the slope of the line.

y + 5 = 0

a 5

b 0

c -5

d undefined

Question 11

Find the slope and the y-intercept of the line.

f(x) = 2x

a m = 2; b = 0

b m = ; b = 0

c m = 0; b = 2

d m = -2; b = 0

Question 12

Find the slope and the y-intercept of the line.

f(x) = x

a m = 2; b = 0

b m = -1/2 ; b = 0

c m = 0; b = 2

d m = 2; b = 0

Answer 1

1. use the point-slope form: y – y1 = m(x – x1)

where slope = m = 3 and x1 = –3, and y1 = 4

then substitute:

y – y1 = m(x – x1)

y – (4) = (3)(x – (–3))

y - 4 = 3(x + 3)

y - 4 = 3x + 9

y = 3x + 4 + 9

y = 3x + 13   ===> b
