Answer:

y = 2x -5

Step-by-step explanation:

Given points: (0,-5)  (1,-3)

(x1, y1) = (0,-5)

(x2, y2) = (1,-3)

Calculate the slope:

m = (y2 - y1)/(x2 - x1)

m = [-3 - (-5)] / [1 - 0]

m = (-3 + 5) / 1

m = 2/1 = 2

Next, the y-intercept is the value of y when x = 0. One of your given points is the y-intercept, (0, -5). The y-coordinate is the value of b.

Therefore, the linear equation is: y = 2x -5

Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall, but its length is unknown. Each section
Firdavs [7]

The expression for the total area of the wall is 10x.

The area of each section is 2x.

<h3>How to find the area of a rectangle?</h3>

The wall is 10 feet tall, but its length is unknown.

The whole wall is rectangular.

Therefore,'

area of a rectangle = lw

where

  • l = length
  • w = width

Therefore, the expression for the total area of the wall is as follows;

area = 10x

The area of each section can be found by dividing the length of the whole wall by 5 and multiplying by 10.

Therefore,

area of each section = x / 5 × 10

area of each section = 10 / 5 x

area of each section = 2x
