Write an equation of the line passing through the points (4.15) and (-1. - 15).

y = 6x - 9

General Formulas and Concepts:

Pre-Algebra

Algebra I

Slope Formula:

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Point (4, 15)

Point (-1, -15)

Step 2: Find slope m

Step 3: Find y-intercept b

Step 4: Write linear equation

Substitute in all variables.

y = 6x - 9

And we have our answer!

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
