QUESTION 3 srry caps were on

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

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

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

Answer 7

y=2x+3 line 1

Answer 8

line 2 same as line 1

Answer 13

Point slope form again

-3-9/3+1= -3

y+1=-3(x-9)

y+1=-3x+27

y=-3x+26

5+1/2+1=2

y+1=2(x+1)

y+1=2x+2

y=2x+1

For your system of equations you have

y={y=-3x+26}
y={y=2x+1}

There is a couple ways you can solve this. You could either use a subtraction method, or a substitution method. since they are both y = something i would just substitute one y in one or the other equation.

2x+1=-3x+26

5x+1=26

5x=25

x=5

So now you just plug in x = 5 for each quotation and you have your y's for both solution points

y=-3(5)+26
y=11

y=2(5)+1
y=11

So this works out nice, your solutions for the set of equations is (5,11) since they are the same points

Answer 14

so its 5 and 11 right

Answer 15

yea

Answer 16

k ill tell if they are right

Answer 17

no i got a 40%

Answer 18

lol

Answer 19

we got 3 wrong
