Question

Complete the equations of the system in slope-intercept form. Use a decimal for the slope if necessary.

Line 1
x y
–3 7
–2 5
Line 2
x y
0 5
2 1

Line 1: y = x +
Line 2: y = x +

Answer 1

@KamiBug

Answer 2

?

Answer 3

what grade and which school??

Answer 4

@k_lynn

Answer 5

well slope intercept form looks like this. \[y=mx +b\]

I'm not exactly good at slope and stuff, so you might want @ganeshie8 or @sleepyhead314 to help you.

Answer 6

ok @Bossimbacon first find the slope for each line, can you do that? :)

\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} } \]when given points (x1, y1) and (x2, y2)

Answer 7

can you teach me how to find the slope?

Answer 8

for example
if you are given two points of
x y
-4 6
-1 -6

then
(-6) - (6) -12
slope = --------- = ----- = -4
(-1) - (-4) 3

using that same order and idea, can you try to find the slope for the lines you were given? :)
just tell me if you don't understand anything ^_^

Answer 9

sooooooooooo is the slope -4?

Answer 10

not quite for your specific question, I was just showing an example for you :)

Answer 11

Line 1
x y
–3 7
–2 5

Answer 12

so that slope set up will be
(5) - (7)
slope = --------- = ?
(-2) - (-3)

Answer 13

would it be 5?

Answer 14

wait it would be 2/5 but how can i minimize that more?

Answer 15

hmmm try that again?
5 - 7 = ?
and
-2 + 3 = ?

Answer 16

-2/5

Answer 17

-2 + 3 = ?

Answer 18

1

Answer 19

right
so you have -2/1 = -2
so the slope for line 1 is m = -2

Answer 20

ohh

Answer 21

now line 1: y = -2x + b
temporarily plug in point (-2, 5) to solve for b

5 = -2(-2) + b can you solve for b from there? :)

Answer 22

um no :(

Answer 23

(-2) times (-2) = ?
