Question

Find the equation of the line of the below:

Answer 1

Answer:

y = -x + 9

Step-by-step explanation:

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

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

(0, 9) y-intercept

(9, 0) x-intercept

Step 2: Find slope m

$m=\frac{0-9}{9-0}$

$m=\frac{-9}{9}$

$m=-1$

y = -x + b

Step 3: Write linear equation

y = -x + 9

Answer 2

Answer:

y = -x + 9

Step-by-step explanation:

Slope Formula:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

(0, 9) y-intercept

(9, 0) x-intercept

Step 2: Find slope m

y = -x + b

Step 3: Write linear equation

y = -x + 9
