Question

Choose the slope-intercept equation of the line that passes through the point shown and is parallel to the line shown below. ' (See attached photo)

A y = 1 over 3x + 14 over 3
B y = 3x + 10
C y = –3x – 2
D y = –1 over 3x + 10 over 3

Answer 1

Do you need help with this?

Answer 2

yes i do @zordoloom

Answer 3

@zordoloom yes i did the problem and came up with B, am I correct

Answer 4

What did you get for the slope of the original line?

Answer 5

And it's not B, because B has positive slope. the line drawn has a negative slope.

Answer 6

And it can't be C, because the equation doesn't intercept the graph at y=2. therefore, the only option that's left is D.

Answer 7

@zordoloom so D is the answer?>

Answer 8

I didn't verify it, But from the list that's the only possible answer. A and B defiantly can't be the answer since the slope is negative. And C intersects at the wrong point. That leaves D as the only option.

Answer 9

And the Slope on D, matches the slope of the plotted line.

Answer 10

@zordoloom hey can you help me with another one?

Answer 11

Sure

Answer 12

Choose the slope-intercept equation of the line that passes through the point shown and is perpendicular to the line shown below. (See attached photo)

A y = 1 over 3 x
B y = –1 over 3 x + 4
C y = 3x + 20
D y = –3x – 16

Answer 13

It's either A or C, which one do you think it is?

Answer 14

@zordoloom i say C, am I correct

Answer 15

Wait, it's asking for a perpendicular line, So it is not A or C, but B or D. Which one do you think it is.

Answer 16

@zordoloom i say D, am I correct

Answer 17

no, because d intersects at y=-16.

Answer 18

That leaves you with only one more choice. I think you can figure that out.

Answer 19

yes B is the answer thanks so much for your help @zordoloom

Answer 20

yep

Answer 21

@zordoloom hey could you help me with another one
