To find the slope, using the coordinates, you will plug them into the slope formula.

Slope formula: \frac{y_2-y_1}{x_2-x_1}

You plug in the 2nd Y-cordinate in y2 and the 1st y-coordinate in y one. Then you do the same thing for the-x coordinates. Plug in the 2nd x-cordinate in x2, and 1st x-cordinate in x1.

You plug in 4 and -1 in the y2 and y1, respectively. Also, you plug in 3 and 2 in x2 and x1 respectively  

The equation you're going to get after plugging in is:

\frac{4-(-1)}{3-2}

4-(-1) is the same as 4+1, so you add them. The subtract 3-2. Then you will end up with the fraction, further solving it will get you your answer.

\frac{4+1}{3-2}=\frac{5}{1}=5

The answer you will get is 5 after completing all of the steps with the slope formula.

The slope of the line is 5

Ghella [55]

Answer:

307.5$

Step-by-step explanation:

150$. 105% of it added.

Since 105% is 1.05, multiply the percentage by the cost to get the money added.

150*1.05=157.5

Then ADD it to the price/savings.

150+157.5=307.5$

Answer:

if angles shown are right angle then from corner to midpoint line if this is symettrical angles are 45 and 45. if area is asked of you need to

Step-by-step explanation:

To find the area of any right triangle, you simply multiply the lengths of the two sides that are perpendicular to each other, and then take half of that. if you could flip one of them and move it on top of the other, they would match exactly. The rectangle has an area of 2 × 4 = 8 square units.

What is the probability that a two-digit number selected at random has a tens digit less than its units digit
Reika [66]

The probability that a two-digit number selected at random has a tens digit less than its units digit is 0.2667 (4/15).

A=24B=90\\\\P=A/B\\\\P=24/90\\p=4/15

There are 90 two-digit numbers (99-9). Of these, six numbers are divisible by 15 (15, 30, 45, 60, 75, 90). This is also divisible by 5. Therefore, the preferred case is 30-6 = 24. Therefore, the required probability is 24/90 = 4/15.

The probability of an event can be calculated by simply dividing the number of favorable results by the total number of possible results using a probabilistic expression. Whenever you are uncertain about the outcome of an event, you can talk about the probability of a particular outcome, that is, its potential.
