Question

graph the equation by plotting three points-3y=5x-7

Answer 1

can someone please help me

Answer 2

so plot 3 points :/

Answer 3

that the thing I don't know what three points to use for x

Answer 4

if you had the 3 points, could you plot them ?

Answer 5

yes

Answer 6

the first thing I would do is divide both sides by -3
to get
\[ y =\frac{5x-7}{-3} \]

Answer 7

pick any value for "x"
any value whatsoever

Answer 8

like 1,0,-1 jdoe001

Answer 9

sure

Answer 10

that's wrong

Answer 11

if you pick x= 1

that means replace x with 1 in the equation
\[ y =\frac{5x-7}{-3} \\ y =\frac{5\cdot 1-7}{-3} \]
now simplify:
5 times 1 is 5
5-7 is -2
you get
\[ y = \frac{-2}{-3} = \frac{2}{3} \]
that means your first point is (1, 2/3)

not exactly pretty, because you have to guess 2/3 of a step for the y-value

Answer 12

can you plot (1, 2/3) ?

Answer 13

I can plot 1 but not 2/3 it has to be a whole number

Answer 14

hehe, the "x" is so-called "independent variable"
why is it called independent? because it can independently take whatever value it pleases

Answer 15

try to "eyeball" it. divide the step into 3rds, and go up 2/3 res
