What is the slope intercept form of the equation of the line?
beks73 [17]

Answer:

The slope-intercept form of the equation of the line is:

y = 2/3x + 2

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the points

  • (0, 2)
  • (3, 4)

(x₁, y₁) = (0, 2)

(x₂, y₂) = (3, 4)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [4 - 2] / [3 - 0]

               = 2 / 3

Thus, the slope of the line = m = 2/3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept b = 2

now substituting m = 2/3 and b = 2 in the slope-intercept form

y = mx+b

y = 2/3x + 2

Therefore, the slope-intercept form of the equation of the line is:

y = 2/3x + 2

Drag the tiles to the correct boxes to complete the pairs. Add each pair of monomials and match it to the correct sum. -15u3 + 5
Grace [21]

Consider the given monomials. Let us determine the sum of these monomials,

1. -15u^3+5u^3

= -10u^3

Therefore, the sum of the given monomials is  -10u^3.

2. 10u^3+(-5u^3)

= 10u^3-5u^3

= 5u^3

Therefore, the sum of the given monomials is  5u^3.

3. 10u^3+5u^3

= 15u^3

Therefore, the sum of the given monomials is  15u^3.

4. 5u^3+(-10u^3)

= 5u^3-10u^3

= -5u^3

Therefore, the sum of the given monomials is  -5u^3.

Answer:

269 and 1/16 feet total (or 269.0625 feet to be precise)

Step-by-step explanation:

20 and 1/2 = 20.5

13 and 1/8 = 13.125

20.5 * 13.125 = 269.0625 feet = 269 and 1/16 feet
