What is the slope of the line passing through (1, 2) and (3, 8)?

slope = 1/7
slope = 1/3
slope = 3
slope = 7

m=3

Step-by-step explanation: Slope is equal to the change in y over the change in x, or rise over run. The change in x is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise). The formula to solve this is m=y2-y1/x2-x1. then you substitute in the values of x and y into the equation to find the slope. now your problem should look like this... m=8-(2)/3-(1)... Then you simplify. simplify both numerator and denominator which should leave you with... m=6/2... then you just divide and get m=3

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
