Graph the line that contains the point (-3,1) with a slope of 2/3

Mathematics
1 answer:
Mila [183]3 years ago
4 0

Answer:

The graph of the line that contains the point (-3,1) with a slope of 2/3.

Step-by-step explanation:

As the line contains the point (-3, 1) with a slop 2/3

Given the slop-intercept form of the line equation

y = mx+b

Here,

  • m = slope
  • b = y-intercept

Substituting the values in the slop-intercept form of the line equation

y = mx+b

1 = \frac{2}{3} (-3) + b

1 =- 2 + b

switching sides

-2+b=1

b=3

Now Substituting the value of b=3 in the slop-intercept form of the line equation

y = mx+b

y=\frac{2}{3} x+3

Hence, the line of the equation will be:  y=\frac{2}{3} x+3

Therefore, the graph of the line that contains the point (-3,1) with a slope of 2/3.

The prediction for average temperature is 53.06° F

Given: The equation for line of best fit:

y = -3.32x + 97.05

What is line of best fit?

Line of best fit is the line that is drawn through the points and it minimizes the error between the actual data and the predicted data.

In a regression graph, there are many scattered points and it becomes very difficult to predict a general equal if we focus on the coordinates and relations of each points. The line of best fit, is a line that passes through the center or from a position where the error between the point and the line is the minimum and it becomes easy to predict or a derive an equation or a relation.

What is a response variable?

A response variable is a variable that is dependent on one or more independent or dependent variables for it's value. So let's say in this equation y = mx + c, y is the response variable as on the change of variable x , y will have different values that is y will response differently for different values of x. Hence y is the dependent variable.

What is predictor variable?

A predictor variable is a variable that is independent of the influence from any other variable, and a change in this variable will give different outcomes. It is called predictor because or a change in it's value we can predict an outcome.

Let's solve the question that is given:

Now y is the response variable and x is the predictor variable.

From the given graph, we see

x = inches of rain

y = average temperature

To make the prediction for x = 13.25, we place the value of x in the equation of line of best fit, that is:

y(13.25) = -3.32*13.25 + 97.05 = 53.06

Hence our prediction or the response for average temperature is 53.06° F

What is 1/2 divided by 1/3
Artemon [7]

Answer:

\frac{3}{2}

Step-by-step explanation:

\frac{1}{2} ÷ \frac{1}{3}

The reciprocal of  \frac{1}{3} is 3, so finding the reciprocal will replace the division sign with a multiplication sign.

= \frac{1}{2} x 3

= \frac{3}{2} or 1\frac{1}{2} or 1.5

Money is borrowed at 15% simple interest. After one year,$1181.05 pays off the loan. How much was originally borrowed?
marin [14]

Answer: $787 was originally borrowed.

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

From the information given,

Total amount = $1181.05

Interest = total amount - principal

I = 1181.05 - P

R = 15%

T = 1 year

Therefore,

1181.05 - P

Therefore,

1181.05 - P = (P × 15 × 1)/100

1181.05 - P = 0.15P

P + 0.15P = 1181.0

1.5P = 1181.05

P = 1181.05/1.5

P = $787
