Question

Which graph represents the equation y − 3.6 = 1.6(x − 1)?

Four graphs
A. Graph A
B. Graph B
C. Graph C
D. Graph D

Answer 1

so lets solve this equation into the form of y=mx+b

Answer 2

do u know how to solve to put into the form of y=mx+b

Answer 3

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)

so in y − 3.6 = 1.6(x − 1)
you can match up and see that x1 = 1 and y1 = 3.6
so a point that the line goes through (x1, y1) is...

Answer 4

idk :( um graph C ? ..

Answer 5

mmm not quite :)
could you name the point I was trying to name?
x1 = 1 and y1 = 3.6
so a point that the line goes through (x1, y1) is...

Answer 6

idk i give up

Answer 7

if x = 1 and y = 3.6
when point (x, y) is... ?

Answer 8

(1,3.6) x(

Answer 9

YES!!! :)
so then which graph has a point at (1, 3.6) ?

Answer 10

Graph a

Answer 11

Correct! :)
