Answer:
The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.

Answer:
-4/5
Step-by-step explanation:
In a line, the slope is the coefficient to x.
In the standard linear equation, f(x) = mx + b, m is the slope.
Since the equation is f(x)= -4/5x + 2, -4/5 is the slope because it is the coefficient to x.
So, the slope is -4/5
Answer:
Step-by-step explanation:
The slope is found by doing the equation 
. When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal 
.
The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.
The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!
Answer:
Step-by-step explanation:
First off, since we're talking about finding the correct hypotenuse for the triangle, we know to use the Pythagorean Theorem:
a^2+b^2=c^2
Since we know from the question, 32 and 22 are not the hypotenuse we know that those two values would be a and b. Now, all we do is stick these both into the equation and solve!
