What is the slope for (2, -1) and (3,1)

Mathematics

VMariaS [17]3 years ago

To find the slope (m), use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}        and plug in the two points

(2, -1) = (x₁, y₁)

(3, 1) = (x₂, y₂)

[lines usually go from left to right, so the point furthest to the left is the 1st point]

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{1-(-1)}{3-2}     [two negative signs cancel each other out and become positive]

m=\frac{1+1}{3-2}

m=\frac{2}{1}

m = 2

Answer: 2

Step-by-step explanation:

m = y2 - y1 /   x2- x1

where slope is m,

so in this case it would be

m= 1-(-1) / 3-2

m=2/1

m=2

Note that you can do it either way

Answer:

$9450

Step-by-step explanation:

We will use compound interest formula:

F=P(1+r)^t

Where

F is future amount [what we want to figure out]

P is present amount [9000]

r is rate of interest [since we want for 6 months, the annual interest divided by 2 is r. So r = 10/2 = 5% or 0.05]

t is the time [ the time period is for 6 months so t = 1 since we already converted the interest rate to 6 month chunk]

Putting in formula, we get:

F=P(1+r)^t\\F=9000(1+0.05)^1\\F=9000(1.05)\\F=9450
