Question

I need help to better understand this worksheet...

Answer 1

Answer:

When you have a equation such as

y = 2x + 4

This means, that whatever x equals, do the rest equation for y. They give you a table, the numbers under x, you replace x with the x in the equation. Multiply it next to the number. Do the rest of the equation, that is how you get y.

Once you do all x numbers, you have to graph it.

X = run

Y = rise

X is the horizontal line

Y is the vertical line

                                               |

                                               |

                                               |

Look at the middle, the x numbers that are to the right of the vertical line are negative.

The ones to the left are positive.

The numbers that are on the top of y are positive

The numbers that are on the bottom are negative.

Hope this helps!
