Question

27. Write the equation of a line that passes through the points ( -2, 5) and (-2, 11) @MathLegend

Answer 1

First, we need a slope.

y2-y1/x2-x1

Answer 2

Can you @kendoll substitute in the proper values?

Answer 3

11-5/-2-2 ?

Answer 4

11-5/-2+2

Answer 5

6/0?

Answer 6

Yes.

Answer 7

thts it
?

Answer 8

No.

Answer 9

so wat we do now

Answer 10

Now, we need to use... point slope form...

y-y1=m(x-x1)

Can you substitute in those values?

Answer 11

no?

Answer 12

y-5=0(x+2)

Answer 13

Can you solve for y?

Answer 14

y-5=0(x+2)
+5 +5

Answer 15

ok so what does y equal?

Answer 16

y=5(x+2)?

Answer 17

@kendoll

y-5=0(x+2)

Remember anything multiplied by 0 is 0...

y-5 = 0
+5 +5
----------
y = 5

Answer 18

y= 5
is your final answer. It can not be y=mx+b since a slope of zero is just a horizontal line.

Answer 19

If this were graphed it would look like...

Answer 20

wat about the x+2 it dissapear
