Find the slope of each graph on the coordinate plane.

To find the slope of a line from a graph, we use the formula:

Slope = Rise / Run

Or more formally:
Slope = (Change in y) / (Change in x)

We pick two points on the line that are easy to read (preferably where the line crosses grid intersections), then calculate how much it goes up or down (rise) and how much it goes left or right (run).

Let’s go through each problem one by one.

Problem 1:

Look at the line. It passes through (-2, 0) and (0, 2). Let’s use those.

From (-2, 0) to (0, 2):

- Rise = 2 - 0 = +2
- Run = 0 - (-2) = +2

Slope = 2 / 2 = 1

✔ Check another pair: from (0,2) to (2,4) → rise=2, run=2 → slope=1. Correct.

Problem 2:

Line passes through (-4, 1) and (0, 3)? Wait — let’s check carefully.

Actually, looking at the graph: when x = -4, y = 1? No — wait, at x = -4, y is about 1? Actually, better to pick clear points.

At x = 0, y = 3 → point (0, 3)

At x = 4, y = 4 → point (4, 4)

Rise = 4 - 3 = +1
Run = 4 - 0 = +4
Slope = 1/4

Wait — let me double-check with another point.

At x = -4, what is y? The line seems to pass through (-4, 2)? Let’s see:

If from (-4, 2) to (0, 3):
Rise = 3 - 2 = 1
Run = 0 - (-4) = 4
→ Slope = 1/4

Yes. So slope is 1/4

But wait — actually, looking again: at x = -4, y = 1? Let me re-express.

Actually, let's use exact grid points.

The line goes through (0, 3) and (4, 4) — yes, that’s clear.

So slope = (4 - 3)/(4 - 0) = 1/4

Alternatively, from (-4, 2) to (0, 3): same thing.

Wait — if at x=-4, y=2? Then from (-4,2) to (0,3): rise=1, run=4 → 1/4.

But let me check the graph again mentally — actually, in many such graphs, they design it so you can count squares.

From any point, move right 4 units, up 1 unit → slope = 1/4.

✔ Confirmed.

Problem 3:

Line goes through origin (0,0) and say (2,-2) or (-2,2).

Use (0,0) and (2,-2):

Rise = -2 - 0 = -2
Run = 2 - 0 = 2
Slope = -2/2 = -1

Check with (-2,2) to (0,0): rise = 0-2 = -2, run = 0 - (-2) = 2 → slope = -1.

✔ Correct.

---

Problem 4:

Line goes through (0,5) and (2,1)? Let’s see.

At x=0, y=5 → (0,5)
At x=2, y=1 → (2,1)

Rise = 1 - 5 = -4
Run = 2 - 0 = 2
Slope = -4/2 = -2

Check another: from (1,3) to (3,-1): rise = -1 - 3 = -4, run = 3 - 1 = 2 → slope = -2.

✔ Correct.

---

Problem 5:

Line goes through (-2,0) and (0,4)? Let’s check.

At x = -2, y = 0 → (-2, 0)
At x = 0, y = 4 → (0, 4)

Rise = 4 - 0 = 4
Run = 0 - (-2) = 2
Slope = 4/2 = 2

Check: from (0,4) to (1,6)? But graph only goes to y=5. From (0,4) to (-1,2): rise = 2-4 = -2, run = -1 - 0 = -1 → slope = (-2)/(-1) = 2.

✔ Correct.

---

Problem 6:

Line goes through (0,0) and (4,-2)? Or (-4,2)?

Use (0,0) and (4,-2):

Rise = -2 - 0 = -2
Run = 4 - 0 = 4
Slope = -2/4 = -1/2

Check with (-4,2) to (0,0): rise = 0 - 2 = -2, run = 0 - (-4) = 4 → slope = -2/4 = -1/2.

✔ Correct.
