Answer:
y = 5/6 x - 6.667
Explanation:
Remark
Your first step is to get the slope of the line on the grid.
The second step is to use slope of the first line that you get and use the point to get the answer.
Slope
A: (1,3)
B: (7,8)
Slope = (y2 - y1)/(x2 - x1)
y2 = 8
y1 = 3
x2 = 7
x1 = 1
Slope = (8 - 3)/(7 - 1)
slope = 5/6
The line so far is y = 5/6 x + b
Use the slope and the given point to get the new line.
y = 5/6 x + b
x = 2
y = -5
-5 = 5/6 2 + b
-5 = 10/6 + b
- 5 - 10/6 = b
- 5 - 1.666 = b
- 6.666 = b
Answer
y = 5/6 x - 6.667
