Answer 1

−1
0
0.5

Answer 2

^^ those are the options

Answer 3

@pooja195

Answer 4

where is the line hitting the y axis? What number? That will be known as out y intercept

Answer 5

*our

Answer 6

The line is hitting the y axis at -1

Answer 7

yeah

Answer 8

Well done :-)

Answer 9

whats next ?

Answer 10

Thats all it only wants you to find the y intrcept

Answer 11

Wait thats it!

Answer 12

LAST ONE!!!

Question:
A line passes through (2, 8) and (4, 12). Which equation best represents the line?

Answer options:
y = 1 over 2 x + 6
y = 2x + 7
y = 2x + 4
y = 1 over 2 x + 10

Answer 13

First find the slope using the slope formula
\[\huge\bf~ \frac{y_2-y_1}{x_2-x_1}=slope\]

Answer 14

12-8=?

Answer 15

12-8=4

Answer 16

4-2=?

Answer 17

2

Answer 18

Good 4/2= ?

Answer 19

2

Answer 20

What's next ?

Answer 21

Btw what time is it where u are @pooja195

Answer 22

Ok now we use the point slope formula
\[\huge y-y_1=m(x-x_1)\]
where
m=slope
(x1,y1)= (2,8)
\[\huge y-8=2(x-2)\]
Ok now isolate y

Answer 23

Whoa whoa what ?!

Answer 24

I'm sorry i feel rlly dumb....... Im the worst at math

Answer 25

It's alright no worries we are all here to learn
I took the info we have
the slope which was 2
and plugged it into the point slope formula which can be used to find the equation of the line in slope intercept form

Answer 26

So im gonna rule out a and d

Answer 27

Good
Ok now we use the point slope formula
\[\huge y-y_1=m(x-x_1)\]
where
m=slope
(x1,y1)= (2,8)
\[\huge y-8=2(x-2)\]
Ok now isolate y
Use the distributive property
