A line passes through the points (-3, 14) and (-1, 16). What is its equation in slope-intercept form?

timurjin [86]

Answer:

y = 6x + 22

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

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 (-3, 14)

Point (-1, 16)

Step 2: Find slope m

Substitute: $m=\frac{16-14}{-1+3}$
Subtract/Add: $m=\frac{12}{2}$
Divide: $m=6$

Step 3: Find y-intercept b

Define: y = 6x + b
Substitute: 16 = 6(-1) + b
Multiply: 16 = -6 + b
Isolate b: 22 = b
Rewrite: b = 22

Step 4: Write linear equation

y = 6x + 22

Explain how you know that the equations 1/4=2x and 1/4/x=2have the same solution

il63 [147K]

the equations 1/4=2x and 1/4/x=2have the same solution

because 1 / 4/ x = 2 can be simplified to

1 / 4 = 2x which is the same with the first equation

Solve for x = 1/8

Then substitute it to the both equation

¼ = 2 ( ¼)

¼ = ¼

2nd equation

1/ 4 /( 1/8) = 2

2 =2
