e-lub [12.9K]

Answer:

y - 7 = 16/13(x - 7)

General Formulas and Concepts:

Alg I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate

y₁ - y coordinate

m - slope

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-6, -9)

Point (7, 7)

Step 2: Find slope m

Substitute: $m=\frac{7+9}{7+6}$
Add: $m=\frac{16}{13}$

Step 3: Write equation

y - 7 = 16/13(x - 7)

-4 = r divided by 20 − 5 Solve for R

Sidana [21]

Answer:

Step-by-step explanation:

Simplify both sides of the equation.

−4= r 20 −5 −4= 1 /20 r+−5 −4= 1 /20 r−5

Flip the equation.

1 /20 r−5=−4

Add 5 to both sides.

1 /20 r−5+5=−4+5

1 /20 r=1

Multiply both sides by 20.

20*( 1 /20 r)=(20)*(1)

r=20
