Question

Which equation has a graph that is parallel to the graph of 15x - 16y = 1?
Select one:
a. 15x + 16y = 1?
b. y = (16/15) x - 7
c. 16x - 15y = 1?
d. y = (15/16) x - 7
-----------------------
Which equation has a graph that is perpendicular to the graph of 3x - 4y = 1?
Select one:
a. 3x + 4y = 1
b. y = (-4/3) x - 7
c. y = (-3/4) x - 7
d. 4x - 3y = 1
-----------------------------
Determine the slope of the line that passes through the points at
(8, 10) and (5, -6).

Select one:
a. 13 / 4
b. 4 / 13
c. -3 / -16
d. -16 / -3
-----------------------
Given the following points find the equation of the line in y = mx+b form.

(14, 158) & (19, 213)

Select one:
a. y = 4x + 11
b. y = 5x + 4
c. y = 11x + 4
d. y = 19x + 4
e. y = 15x + 5

Answer 1

okay so parallel equations have the same slope

Answer 2

so get y by itself and tell me what you think the answer is?

Answer 3

actually just tell me what you think the answer is

Answer 4

i think its b or d

Answer 5

15x - 16y = 1?

Rewrite this equation to be in the form of y= mx + b
m would be the slope and b is the y-intercept

Once you write it in that form, you know the slope. Parallel lines have the same slope so we just need to find an answer choice that has the same slope as the equation

Answer 6

the slope is 15/16

Answer 7

correct

Answer 8

now which answer choice has a slope of 15/16

Answer 9

b and d

Answer 10

no just D

Answer 11

thanks
