Answer:

You are correct.

Step-by-step explanation:

The x-intercept could be written the way you have or also it can be written as a point (-1, 0).

The y-intercept could also be written as a point (0, -2) But they are commonly written the way you have also.

So, the slope is -2. But just to be clear. That slope of -2 has nothing to do with the y-intercept of -2.

If you mark all the points on the line, to get from one point to the next point, you go down 2 and over (positive direction) 1. The down 2 in math is -2 and the over 1 is just 1. The slope is that ratio of -2/1.

Slope tells us if the line is going up or down, steep or flat, even horizontal. It was coincidence only that the y-intercept and slope were the same number.

Wittaler [7]

Answer:

New price of the stock = $42

Step-by-step explanation:

Given

Price of stock at the start of the day = $35

Increased by 20% by the end of the day.

To find the new price of the stock which is the price of the stock at the end of the day.

Solution:

Price at start =$35

Increase Percent at the end = 20%

Amount of increase in price = Increase\ percent \times start\ price = 20\% \times 35 =0.2\times 35=\$7.0

∴ New price at the end of the day = Start\ price + increase\ in\ price= \$35+\$7=\$42

Question in pic. please answer!
Aleksandr [31]

Answer:

The angles from largest to smallest are:

∠A

∠B

∠C

Step-by-step explanation:

We can see in the diagram that

AB = 7

AC = 8

BC = 9

The angles opposite to sides are as follows:

∠A is opposite to BC

∠B is opposite to AC

∠C is opposite to AB

The angle opposite to the largest side of the triangle is the largest and the angle opposite to smallest side of the triangle is the smallest in measurement

Arranging the sides from largest to smallest:

BC, AC, AB

Similarly the angles opposite them will be arranged according to them

∠A, ∠B, ∠C

Hence,

The angles from largest to smallest are:

∠A

∠B

∠C
