please leave

Answer 2

@MathGuyThatWantsHelp can u help me

Answer 3

y- y1 = m (x -x1)

Answer 4

Here r the answers

y = 2x + 5
y = 4x + 8
f(x) = 2x + 5
f(x) = 4x + 8

Answer 5

please someone help me

Answer 6

m = y2-y1/x2-x1
lets suppose x1, y1 = (1,7) and x2, y2 = (5,15)
then m (the slope) = (15-7)/5-1 = 8/4 = 2

Answer 7

yep

Answer 8

so which one would it be i didn't really understand this concept during school @BPDlkeme234

Answer 9

i need help!!!!!!!!!!!!!!!!111

Answer 10

@BPDlkeme234

Answer 11

please help me dude

Answer 12

so, x1, y1 = (1,7) and (x2, y2) = (5, 15)
this is known as the point-slope form of the equation.
therefore the eq. of the line is : y-(7) = 2(x-1)
y-7 = 2x -2

Answer 13

now, if we add 2 to both sides we get:
y-7 (+2) = 2x -2 (+2)
y-5 =2x
y= 2x + 5
is that one of your answers?

Answer 14

no the Answers are

y = 2x + 5
y = 4x + 8
f(x) = 2x + 5
f(x) = 4x + 8

Answer 15

eh, yes it is equal to the first answer y=2x + 5
