Mathematics
1 answer:
m_a_m_a [10]3 years ago
7 0

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3

In a graph what function is a nonvertical line or part of a nonvertical line.
timama [110]
A function cannot have multiple outputs (y-values) for any given input (x-values). For example, y=2x+3 is a function because no mater what number x represents, there is a single, unique y-value (When x=3 y=9 ). In other words, you can never have two (or more) y-values that correspond to a single x-value. Therefore, a vertical line, for example x=2, cannot be a function because it has an infinite amount of y-values for a single x-value. A horizontal line is a function because there is only one y-value for any given x-value. For example, y=3. No mater what x-value is used, there is only one y-value possible (in this case, y will always equal 3). I am, of course, referring to the cartesian coordinate system, also known as the rectangular coordinate system

1.What is the slope of (0,2) and (-8,-8). What is the slope of (-8,-5) and (8,15)
ss7ja [257]

Answer:

Slope of (0,2) and (-8,-8):    5/4

Slope of (-8,-5) and (8,15):   5/4

Both slopes are 5/4

m = 5/4

Step-by-step explanation:

To find the slope:

1. Use the formula  m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} .

2. Assign point 1 and point 2

3. State (x₁ , y₁) and (x₂, y₂)

4. Substitute x₁ , y₁, x₂, and y₂ into the formula

5. Solve

Slope of (0,2) and (-8,-8):

Point 1: (0,2)        x₁ = 0     y₁ = 2

Point 2: (-8,-8)     x₂ = -8   y₂ = -8

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}         Formula for slope

m = \frac{-8-2}{-8-0}           Substituted points

m = \frac{-10}{-8}          Simplified the subtraction then the negatives

m = \frac{10}{8}          Reduce fraction by dividing top and bottom by 2

m = \frac{5}{4}              First slope

Slope of (-8,-5) and (8,15):

Point 1: (-8,-5)     x₁ = -8    y₁ = -5

Point 2: (8,15)     x₂ = 8     y₂ = 15

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}            Formula for slope

m = \frac{15-(-5)}{8-(-8)}         Substituted points

m = \frac{15+5}{8+8}             Simplified the subtraction into addition

m = \frac{20}{16}                Reduce fraction (divide top and bottom by 4)

m = \frac{5}{4}                 Second slope
