What is the approximate line of best fit for the scatter plot

The first one, or y= -x + 8

Step-by-step explanation:

You can rule out the last one, because there is no y intercept. If there was no y intercept, the dots would be passing through the origin (0).

The one with -8 is not right because the y intercept is positive 8. If you count on the y axis (up 8), it matches with the overall direction of the line.

The line/ slope of this scatter plot is negative, so the only one that makes sense would be the first one. Going up and from right to left is a positive slope. Going down from left to right is a negative slope.

0 is its x and y coordinate

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
