Answer:

Slope: 16

y-intercept: (0, 0)

<u>Yes</u> it is proportional

Step-by-step explanation:

<h2>What's the slope</h2>

To find the slope we can do rise over run.

192 - 96 96

----------------- = ----------- = 16

12 - 6 6

So the slope is 16

<h2>What is the y-intercept?</h2>

For the y intercept we can just look where the line crosses the y-line so (0, 0)

We can check that by inputing some numbers:

y = mx + b -------> 96 = 6 · 16 + b

96 = 96 + b

- 96 - 96

0 = b

in this equation b represents the y-intercept

<h2>Is it proportional?</h2>

And the definition of a proportional slope is if the equation is y = mx, which in this case it is true, as the equation is y = 16x. (m is the slope which we've already found above)

So evidently the slope is proportional.

The slope is 1, so put either “x” or “1” and the y-intercept is at the origin so it’s 0, so put “(0,0)”

Answer:

OPTION A: 2x + 3y = 5

Step-by-step explanation:

The product of slopes of two perpendicular lines is -1.

We rewrite the given equation as follows:

2y = 3x + 2

⇒ y = $\frac{3}{2}x + 1$

The general equation of the line is: y = mx + c, where 'm' is the slope of the line.

Here, m = $\frac{3}{2}$ .

Therefore, the slope of the line perpendicular to the line given = $\frac{-2}{3}$ because $\frac{3}{2} \times \frac{-2}{3} = -1$ .

To determine the equation of the line passing through the given point and a slope we use the Slope - One - point formula which is:

y - y₁ = m(x - x₁)

The point is: (x₁, y₁) = (-2, 3)

Therefore, the equation is:

y - 3 = $\frac{-2}{3}$ (x + 2) $

⇒ 3y - 9 = -2(x + 2)

⇒ 3y - 9 = -2x - 4

⇒ 2x + 3y = 5 is the required equation.

Find the annual percent increase or decrease that y = 0.35(2.3)x models. (1 point) A.230% increase B.130% increase C.30% decreas

ipn [44]

Answer: B. 130% increase

Step-by-step explanation:

Given function : $y=0.35(2.3)^x$

If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.

This function is equivalent to the exponential growth function

$y=A(1+r)^x$ , where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]
