What is the equation of the line that passes through the point (8,-8) and has a slope of -1
marishachu [46]

Answer:

y= (-1)*x

Step-by-step explanation:

lets assume that the line equation is

y=m*x +b

where m is the slope and b the independent variable that intercept Y axis.

then replacing the value of m:

y=(-1)*x + b

after that we have to look for the value of b. Its obtained replaicing the given point (8,-8):

-8 = (-1)*(8) +b

-8 = -8 + b

0 = b

Therefore the equation of the line is:

y= (-1)*x

Which expression is equivalent to this expression? x(2x 3) Question 1 options: 2x2 3 2x2 3x 2x2−3x 3x 3.
mash [69]

The expression is equivalent to this expression is  2x^2+3x.

The correct option is A.

Given

The expression is;

= x(2x + 3)

<h3>What is the algebraic expression?</h3>

Algebraic expressions consist of numbers and variables along with operational signs.

The equivalent expression is found by multiplying x and simplifying.

Therefore,

The expression is equivalent to this expression is;

\rm = x(2x + 3) \\\\= 2x\times x+ 3 \times x\\\\= 2x^2+3x

Hence, the expression is equivalent to this expression is  2x^2+3x.

PLEASE HELP!!!
Kaylis [27]

ANSWER

A reflection over the y-axis followed by a dilation by a factor greater than 1

EXPLANATION

We can see from the diagram that, square M and square P are all equal distance from the line y-axis.

This means that square M has been reflected in the y-axis.

Since square P is greater than square M, there has been a multiplication by a scale factor greater than 1.

The correct choice is B.
