(3, -5)(0, 4) Write the equation of a line using the point slope formula

Serga [27]

Answer:

y = - 3x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (0, 4)

m = $\frac{4-(-5)}{0-3}$ = $\frac{4+5}{-3}$ = $\frac{9}{-3}$ = - 3

The line crosses the y- axis at (0, 4) ⇒ c = 4

y = - 3x + 4 ← equation of line

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

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

Step-by-step explanation:

Step 1: Define

Point (40, 3000)

Point (60, 4000)

Step 2: Find slope m

Substitute: $m=\frac{4000-3000}{60-40}$
Subtract: $m=\frac{1000}{20}$
Divide: $m=50$
