First group terms together- polynomial
(2ax-4x) + (2y-ay)

common factor for first term is 2x and the second term is y

2x(2a-4) + y(2-a)
2x(a-2)  + y(2-a)

Add like terms which yields final answer
 
(2x+y)(2-a)

Use the order pairs to find the linear equation in slope intercept form<br> (0,10) &amp; (3,2)
Virty [35]

y = \frac{-8}{3}x + 10 is the equation in slope intercept form

<em><u>Solution:</u></em>

Given points are (0, 10) and (3, 2)

We have to find the slope intercept form

Let us first find the slope of line

<em><u>The slope of line is given as:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

Here,

(x_1, y_1) = (0, 10)\\\\(x_2, y_2) =(3,2)

<em><u>Substituting the values we get,</u></em>

m = \frac{2-10}{3-0}\\\\m = \frac{-8}{3}

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Substitute m = \frac{-8}{3} and (x , y) = (0, 10) in eqn 1

10 = \frac{-8}{3} \times 0 + c\\\\c = 10

Substitute\ m = \frac{-8}{3}\ and\ c = 10\ in\ eqn\ 1

y= \frac{-8}{3}x + 10

Thus the equation of line in slope intercept form is found

Which function can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the
hodyreva [135]

The function representing the height is y = 36 - \frac{3}{4} x.

<h3>What is function?</h3>

A formula, rule, or legislation that specifies how one variable (the independent variable) and another variable are related (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

<h3>What is fraction?</h3>

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

Given that,

Height of rails h is 36in.

The rate of decrement is 9 inches for every 12 horizontal inches,

We represent the rate (r) as a fraction.

r = -\frac{9}{12} (negative, because it decreases),

r = -\frac{3}{4},

So, the function is

Y = h + r × x

Where,

X is distance from top

So, y = 36 -\frac{3}{4}x
