y = x - 6

Step-by-step explanation:

All of these equations are written in the slope intercept from: y = mx +b where m is the slope and b is the y intercept. Slope = rise / run = change in y /  change in x. For this graph the slope is 1. The y-intercept is where the graph crosses the y-axis, for this question the y-intercept is -6.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
