What is the equation in slope-intercept form that passes through the points (-4, 47) and (2, -16)?

Whitepunk [10]

Answer:

y = 10.5x - 37

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Equality Properties

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

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (-4, 47)

Point (2, -16)

Step 2: Find slope m

Substitute: $m=\frac{-16-47}{2+4}$
Subtract/Add: $m=\frac{63}{6}$
Simplify: $m=\frac{21}{2}$

Step 3: Find y-intercept b

Define: y = 21/2x + b
Substitute: -16 = 21/2(2) + b
Multiply: -16 = 21 + b
Isolate b: -37 = b
Rewrite: b = -37

Step 4: Write linear equation

Combine all parts.

y = 21/2x - 37

y = 10.5x - 37

And we have our final answer!

Pls help its my last question?!?!

OlgaM077 [116]

Answer:

x = -11

m<B = -43

m<C = -22

Step-by-step explanation:

To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.

I hope this is correct and helps!
