write an equation in slope-intercept form of the line that passes through the given points (-4,-2) (8,-2)

Answers

Answer:

y=-2

Step-by-step explanation:

First, find the slope using the slope formula: m=y2-y1/x2-x1

Plug the numbers into the equation and get 0

Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)

y+2=0(x+4)

Distribute and simplify to get the final answer.

y+2=0+0

y=-2

So you would graph the two points to make the line, then find the slope by doing rise/run. The slope equation is y=mx +b and m is slope so u would plug that in. Then you would find the y-int / b by finding the point on the line where it crosses the y acis/ when x is zero! There u hv it!

The algebraic expression -5x+6y-3/x is not a polynomial.

The given polynomials are 7-z, 2p³q²-pq³ and -5x+6y-3/x.

What is the polynomial?

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here,

In 7-z has non-negative integer as exponent

So, it is a polynomial

In 2p³q²-pq³ has non-negative integer as exponent

So, it is a polynomial

In -5x+6y-3/x has negative integer as exponent, which is [tex]x^{-1}[/tex]

So, it is not a polynomial

Hence, the algebraic expression -5x+6y-3/x is not a polynomial.
