Question

What is the slope of the line passing through the points (0, -5) and (4, 2)?

Answer 1

@shansha1

Answer 2

Also what is the slope 3x+4y=12

Answer 3

slope = rise/run
=\[\frac{ y2-y1 }{ x2-x1 }\]

Answer 4

So.... what does that mean?

Answer 5

so here we have (0, -5) and (4, 2 )
(0,-5) =(x1,y1)
(4,2)=(x2,y2)
put these values in the eq you will get the answer

Answer 6

try to do if there is still any problem let me know :)

Answer 7

Do I have to graph it? I really suck at graphing!!!

Answer 8

no it is not required in the question just solve it

Answer 9

I have no idea what to do

Answer 10

(0,-5) =(x1,y1)
(4,2)=(x2,y2)
put these values in the following equation :
\[\frac{ y2-y1 }{ x2-x1 }\]

Answer 11

So I have to figure out what y2 and so on equals?

Answer 12

you have y2 just put the values
for example

(1,2) (3,4)
here (x1,y1) are (1,2)
and (x2,y2) are (3,4)
formula is
\[\frac{ y2-y1 }{ x2-x1}\]
putting the values
\[\frac{ 4-2 }{ 3-1 }\]
2/2=1

Answer 13

so you would substitute and then simplify?

Answer 14

yup :)

Answer 15

:) Thanks so much! and 0 would = y1 and -5 would = x1 4 = x2 and 2 =y2?

Answer 16

x1= 0
y1=-5
x2=4
y2=2

Answer 17

my pleasure :)

Answer 18

@smilie2015 is a lifesaver!!!
