Answer:
This is the graph I inputted into desmos.
Step-by-step explanation:
Next time, using a graphing calculator will work! However, making a table for the x and y outputs will also make it easier to graph points.
For example: see attached image of table.
2 and 3/5 pounds of steak, is 2.6 pounds of steak.
Multiply that with the cost per pound.
2.6 x 6.10 = $15.86
You can find the slope either by just looking at the line or using the slope formula.
#1: The slope formula is:
Find two points and plug it into the formula
I will use (0, 2) and (1, -1)
(0, 2) = (x₁, y₁)
(1, -1) = (x₂, y₂)
[two negatives cancel each other out and become positive]
m = -3
#2: To find the slope without having to do the work, you use this:
Rise is the number of units you go up(+) or down(-) from each point
Run is the number of units you go to the right from each point
If we start at a defined/obvious point, like (0, 2), find the next point and see how many units it goes up or down and to the right. The next point is (1, -1), so from each point, you go down 3 units and to the right 1 unit. So your slope is -3/1 or -3. You can make sure the slope is right by looking at another point.
False.
A point has no width, height, or length.
