Question

Can someone help me with a few questions??!
I have issues with slope!

Answer 1

Can you post one of the questions.

Answer 2

What is the slope of the line that passes through the given points?
(3,2) and (5,12)
a. 5
b. -5
c. -1/5
d. 1/5

Answer 3

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 4

in your question,
x1= 3
y1 = 2
x2 =5
y2 =12

Answer 5

so 2-12/3-5

Answer 6

yes
don't forget the brackets
(2-12)/(3-5)

Answer 7

-10/-2=5

Answer 8

good!
\(\huge \checkmark\)

Answer 9

Can you help with some more?

Answer 10

sure :)

Answer 11

What is the graph of the equation?
2x-y=2

Answer 12

it would be a line.

to get the intercepts of that line
plug in x= 0, find y
plug in y= 0 find x

Answer 13

How do I plug it in? Sorry I am lost..

Answer 14

2x- y =2

to get x intercept, we put y =0
2x = 2
x =1

so x intercept is 1,0

can you now find y intercept ? put x= 0 in 2x-y =2

Answer 15

y=0

Answer 16

-y = 2

so y =-2

y intercept is 0,-2

Answer 17

now the points 1,0 and 0,-2 should lie on the graph.

which graph has these 2 points?

Answer 18

C

Answer 19

correct :)

Answer 20

Write an equation of the line, in point slope form that passes through the two given points: (-2,15) and (9,-18)
a.y-2=-3(x-15)
b.y-2=-1/3(x+15)
c.y-15=-3(x+2)
d.y-15=-1/3(x+2)

Answer 21

first find the slope using the above formula.

x1 = -2
y1 = 15
x2 = 9
y2 = -18

Answer 22

-11/33=3

Answer 23

-11/33 is -1/3

Answer 24

Oh yeah sorry..

Answer 25

so the equation would be

y-y1 = m (x-x1)

y -15 = -1/3 (x+2)

Answer 26

Thank you! I have 8 more can you help? I am starting to understand!
