Consider the equation y=-2x+5. Describe everything you know about this graph compared to the parent linear function y=x.​
Mekhanik [1.2K]
Function y = -2x + 5:
slope of -2
y intercept at 5
x intercept at 2 1/2

function y = x
slope of 1
y intercept at 0
x intercept at 0

Is this a linear function? One person sends an email to 2 people. Those 2 people send it to 4 people, and those 4 send it to 8 p
Mumz [18]
Yes; this is a linear function because you plug in a number and multiply it by two, so the function would be y=2x, which is linear despite the fact that it lacks a b value.

Hope this helps! :)

Which one is it , help me on this please please please please please please please
snow_tiger [21]

Answer:

D

Step-by-step explanation:

7^-2 = 1/7^2

The negative means you flip it

1/7^2 times 7^6 is 7^6/7^2 (just multiply).

using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)

D is the only one that equals 7^4, as 2 times 2 is 4.

From Apex Algebra 2!! HELP!!! I’ll rate you the brainliest :) (Part 1 and 2)
ivann1987 [24]

slope (m ) = \frac{5}{2} , y - 1 = \frac{5}{2} ( x - 2)

The equation of a line in ' point- slope form 'is

y - b = m (x - a)( m is the slope and (a , b ) a point on the line )

To calculate m use the ' gradient formula'

m = (y₂ - y₁ )/(x₂ - x₁ )

let (x₁, y₁ ) = (2 , 1) and (x₂, y₂ ) = (14 , 31) ← values chosen from table

m = (31 - 1 )/(14 - 2 ) =\frac{30}{12} = \frac{5}{2}

equation in point- slope form using m = \frac{5}{2} and (a,b )= (2 , 1)

y - 1 = \frac{5}{2} ( x - 2)
