Question

@phi

Answer 1

Points C and D lie on graph of the equation y = 1.3x.

What are the y-coordinates for each point?

Point C: (3, ) Point D: (−6, )

Answer 2

Do you know how to do this ?

Answer 3

um........ ........................... ....................no :3 sorry i really am sorry :(

Answer 4

my teacher is not online today so i can not ask her to help me

Answer 5

y = 1.3x
means
y is 1.3 times x
if x were a number, you would do 1.3 times that number

Answer 6

oh i understand so 3*1.3 and -6*1.3?

Answer 7

yes.

Answer 8

sweet i did it so y1=3.9 and y2= -7.8

Answer 9

yes.
and if you plot (3,3.9) and (-6,-7.8)
you can form the line (by connecting the dots)

Answer 10

right so it is a positive slope or wait negative? i know it is not part of the question but witch one is it?

Answer 11

positive slope means the line goes up as you move to the right.

if you are at (-6,-7.8) and move to the right and end up at x=3, the y is 3.9 which is above -7.8
the line is going up as we move to the right
so it has positive slope

Answer 12

right can you help me another i will post new question :)

Answer 13

if we want to find the slope we would find change in y
3.9 - -7.8 = 11.7
and divide by change in x
3 - -6 = 9
11.7/9 = 1.3 or 13/10

Answer 14

right right i understand now thank you so much you should be a math teacher :)
