Answer:
The equation in point-slope form is
.
Step-by-step explanation:
We are given the slope and a coordinate pair of a line.
- Slope: 2
- Coordinate Pair (x, y): (4, 6)
Therefore, we can now label our coordinate pair and substitute our values into the formula. Our formula is:

We can label our coordinate pairs with the
labeling method.
Therefore, since our two coordinates are:
We can label 4 as x₁ and 6 as y₁.
Then, we are able to determine <em>m</em>, or our slope.
Now, let's set up our equation.

Therefore, our line is y = 2x - 2. However, the problem asks for it in point-slope form. So, this is exactly what we have in Step 2: y - 6 = 2(x - 4).
Caitlin = 20 laps
Hannah = 4/5 as many laps
Multiply the laps swan by Caitlin (20) by 4/5
20 x 4/5 = 80/5 = 16
Hannah swam 16 laps
Answer:
in bold
Step-by-step explanation:
M is the slope and b is the y intercept
1 looks correct
2. Chose 2 points; I chose (0,2) and (2,2) Find slope: 0/-2=0 y=mx+b y=0x+b y=b b=2 y=2
3. Chose 2 points: I chose (2,9) and (0,5) Find slope: 4/2=2 y=mx+b y=2x+5
4. Chose 2 points: I chose (0,-2) and (2,-3) Find slope: 0--3/-2-2=3/-4 y=mx+b y=-3/4x-2
