Question

Choose the slope-intercept equation of the line that passes through the point (-2, 2) and is parallel to y = 4x + 7.

y-4x+10

y=1/4x +2/5

y=-4x - 6

y= -1/4x + 3/2

Answer 1

is the first one y= -4x+10?

Answer 2

Parallel lines have same slope. Which line has same slopwe with y=4x+7?

Answer 3

yes sorry

Answer 4

okay so therefore it can be either 1 or 3

Answer 5

its 3

Answer 6

i say 3

Answer 7

so you take each equation and you substitute the coordinates it into the two choices

Answer 8

2=-4(-2)-6
2= 8 -6
2=2

Answer 9

Choose the slope-intercept equation of the line that passes through the point shown and is perpendicular to the line shown.


y = 1/3x

y = -1/3x + 4

y = 3x + 20

y = -3x - 16

Answer 10

perpendicular lines are negative reciprocals

Answer 11

are you talking about the new problem i posted

Answer 12

so its number 2

Answer 13

yeah

Answer 14

the line perpendicular to 3x would be -1/3x

Answer 15

Consider the line that passes through the points (-5, 9) and (-2, 0). Below are two different equations. Identify the true statement concerning both equations.

equation1: y-9=-1/3(x+5)
equation2: y - 9 = -3(x + 5)

Only equation #1 represents the line that passes through the two given points.

Only equation #2 represents the line that passes through the two given points.

Both equation #1 and equation #2 represent the line that passes through the two given points.

Neither equation #1 nor equation #2 represents the line that passes through the two given points

Answer 16

@salgai

Answer 17

sub in the coordinates into the equations

Answer 18

and its pretty simple which statement is correct

Answer 19

c?

Answer 20

let me check one second

Answer 21

ok

Answer 22

its b

Answer 23

aww how

Answer 24

the slope of the line is -3 and only the first equation has a slope of -3

Answer 25

Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3.

y - 2 = -3(x + 7)

y + 7 = -3(x - 2)

y + 2 = -3(x - 7)

y - 7 = -3(x + 2)

Answer 26

Here are the steps
1) for all the possible answers, you will have to isolate the variable "y"
2) than you can check the slope for each, by checking the value of the constant before the x value (it has to be -3)
3) Now you have to substitute (7,-2) into the equations to see which ones fit. So, substitute 7 for x and -2 for y.
4) The correct answer is the one that balances.
