The slope of the line below is 1. write the point-slope equation for the line using the coordinates of the labeled point. 7,8

SOLUTION:

General equation : (y2 - y1)/(x2 - x1) = slope

.

Substitute slope = 1 into the equation:

(y2 - y1)/(x2 - x1) = 1

.

Substitute (7, 8) into the equation:

(y - 8)/(x - 7) = 1

.

Cross multiply:

y - 8 = x - 7

.

y - 8 = x - 7

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
