How do you graph y=3x-4 on a coordinate grid

mars1129 [50]

Answer:

You can look at the screenshot

Step-by-step explanation:

So one point of the line is (0, -4) and another point is (4/3, 0). Plot these points on a graph and draw a line.

0, -4 is from making x = 0, and then 4/3, 0 is from making y = 0.

-15.6 = -3.9r please include an explanation of how you got your answer :) thanks

Mumz [18]

Here is the equation:

$-15.6 = -3.9r$

Since both decimals are negative, the answer will be positive.

Negative times Negative = Positive

Divide both sides by -3.9 to leave the variable alone:

$-15.6 \div -3.9 = -3.9r \div -3.9 \\ 4 = r$

r is equal to 4 → r = 4
