Find the slope of the line graphed below.
2 answers:
There are two ways you could calculate slope.
The first is using two points on the line. Plug the coordinates into the formula:
y₁ - y₂ / x₁ - x₂
This is the difference in rise divided by the difference in run, or rise/run. Our marked coordinates are (-2, -3) and (0, 1).
y₁ - y₂ / x₁ - x₂
-3 - 1 / -2 - 0
-4 / -2
2
The second method is much faster: Look at the graph; count the amount of units the graph rises and the amount of units the graph runs, then divide the former number by the latter number (see attachment).
4 / 2 = 2
Answer:
Slope = 2
