What is the answer??​
Gelneren [198K]

Answer:

y= 4x+3

Step-by-step explanation:

To write your equation, solve for the slope.

(y2-y1)/ (x2-x1)

Find two coordinate points from the table.

(0,3) (1,7)

(7-3)/ (1-0)= 4

m=4

Use point-slope equation to find your equation.

(y-y1)=m(x-x1)

(y-3)=4(x-0)

y-3= 4x

y= 4x+3

Is the expression below a perfect square trinomial or the difference of two squares?
DanielleElmas [232]

The expression shown below is a difference of two squares.

<h3>Is a given expression a perfect square trinomial or a difference of two squares?</h3>

In this problem we have an algebraic expression that has to be checked by algebraic procedures. The complete procedure is shown below:

(x² + 8 · x + 16) · (x² - 8 · x + 16)                  Given

(x + 4)² · (x - 4)²                                           Perfect square trinomial

[(x + 4) · (x - 4)] · [(x + 4) · (x - 4)]                 Definition of power / Associative and commutative property

(x² - 16)²                                                      Difference of squares / Definition of power / Result

The expression shown below is a difference of two squares.

Please help i have a test and this is the only question im stuck on 30 points
tia_tia [17]
It’s D because the line is on the positive side of the graph. The y-intercept is positive 5 and x-intercept is positive 4, which makes a slope of 5/4.

Hope this helped:)
