Answer:1. the first line of numbers is the x axis, so you would plot it left and right. the second line of numbers is the y axis, so you would plot it up and down. Then, you find the intercepting point of the points if you draw lines up and down, left and right for each one of the points.
2. The slope-intercept formula is y=mx+b, and the x and y are two points on the graph, while b is slope, and m is the y-intercept.
3. The slope is how much up-or-down a line in a graph is going. if it is positive, then the line will go up. if it is negative, it will go down. The y-intercept is where the line in a graph intercepts with the y-axis.
6. The arm span of a 66 inch tall person is also 66 inches
7. The arm span of a 74 inch tall person is also 74 inches
Step-by-step explanation: The reason for this is, the height of a person is also the persons arm span. It is scientifically proven that when you grow, you arm span grows at the same rate.
