There’s a lot of stress going around with online schooling, if this is your subject of struggle hope this helps:
A negative times a negative is a postive
A negative times a positive is a negative
A negative plus a negative is a negative
( just add the numbers like normal and keep the negative sign)
A positive plus a negative is the same as subtraction and take the sign of the larger number
F(x) =5x+7
x,y
y=F(x) ( y and F(x) are the same thing basically)
Plug 1, then 2 , then 3 into the formula: 5x+7
because 1, 2, and 3 are your x’s
5(1)+7= 12, 5(2)+7= 17, 5(3)+7= 22
Your f(x)’s aka y’s= 12, 17, and 22
X( x’s) y’s ( for y coordinate)
| 1 | 12 |
| 2 | 17 |
| 3 | 22 |
Your coordinates to graph:
( 1,12) x=1 y=12
(2,17) x=2 y=17
(3,22) x=3 y=22
To Graph:
Start with your first points: (1,12)
On a graph go to one on the x-axis (the horizantal flat axis,) and go up 12 and make a dot… ( 1,12)
Then go to two on the x-axis and up to 17 on the y ( vertical axis and make a dot. (2,17)
Last go to 3 on the x-axis an up to 22 and make a dot …
(3,22)
Connect the dots for your graph
May God bless!
