Answer:

y = mx + b

Step-by-step explanation:

y represents the dependent variable (value you are getting).

m represents the slope of the line.

x represents the independent variable (what you are changing).

b represents the y-intercept, or the y value when x is zero.

Find the percent of increase or decrease from the first number to the second number. 140 to 84
tresset_1 [31]
We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:

140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)

solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.

Let me know if I can clear anything else up.

Mario made a table with the rules below
Lady_Fox [76]
  • It will be option A.
  • x - coordinate is 1. If we multiply 3 with 1, it will be 3. And if we multiply 3 with 3, it will be 9.
  • y- coordinate is 1. If we add 3 with 1, it will be 4. And adding 3 with 4, we get 7.

<u>Answer:</u>

<u>a- (1,1) (3,4) (9,7)</u>

Hope you could get an idea from here.
