Question

Find the equation of the line of the below:

Answer 1

y = -x + 9

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

Answer 2

y = -x + 9

Explanation:

Slope Formula:
`m=(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=(0-9)/(9-0)`

`m=(-9)/(9)`

`m=-1`

y = -x + b

Step 3: Write linear equation

y = -x + 9
