Question

what is the slope of the line passing through the points (2,7) and (1-,3)?

Answer 1

Can someone explain i keep getting 4 over 1

Answer 2

m = (y2 - y1)/(x2-x1)
m = (-3-7)/(1-2)
m = -10/-1
m = 10

Answer 3

2 over 7
3 over 4
4 over 3
1 over 3
are the possible answers how would i simplify 10?

Answer 4

Where did you get that? No other answer rather than 10.

Answer 5

is that 2nd point supposed to be (-1, 3)?

Answer 6

@Yttrium u wanna redo?

Answer 7

yea

Answer 8

it should be
m = (3-7)/(-1-2)
m = -4/-3
m = 4/3

Answer 9

what is the correct equation of the line shown below?

Answer 10

m = (3-(-3))/(0-(-4))
Try to evaluate that.

Answer 11

- 3 over 2 x - 3?

Answer 12

I don't really know how to evaluate it. but out of the 4 possible answers that seems like the best answer.

Answer 13

m = 6/4 or 3/2

Answer 14

How did arrive that? Simple, just let P1 to be (-4,-3) and P2(0,3)\
then \[m = \frac{ 3-(-3) }{ 0-(-4) } = \frac{ 6 }{ 4 } = \frac{ 3 }{ 2 }\]

Answer 15

these are the possible choices. So after i find out that it's 3 over 2 how do i find the rest out

Answer 16

That's already the equation e. Okay.
Using point (0,3),
y - 3 = 3(x-0)/2
y = (3x/2)+3 --> A

Answer 17

The x-intercept of a line is -5 and the y-intercept of the line is -2. What is the equation of the line?

Answer 18

I would think 5 over 2 but then i wouldn't know how to do the rest

Answer 19

so how do i know if it is x - 5 or x - 2

Answer 20

y-0 = 5(x+5)/2
y = (5x/2) + 5

Answer 21

Last one
What is the slope-intercept form of te equation y-7 = -5/\[y-7 =- \frac{ 5 }{ 2}(x+4)?\]

Answer 22

just solve it , open the brackets , etc
