Answer to Q1:

A.   The slope is 5.

Step-by-step explanation:

From question statement , we observe that

Two point passing through the line are given.We have to find slope of line.

(x₁,y₁) = (8,3)  and (x₂,y₂) = 9,8)

Slope = ?

The formula to find slope of line is:

slope = y₂-y₁ / x₂-x₁

Putting given values in above formula, we have

slope = 8-3 / 9-8

slope = 5 / 1

slope = 5  which is the answer.

Answer to Q2:

Choice A is the answer.

Step-by-step explanation:

Slope of line tells the behaviour of line.

If slope is positive . the lines rises from left to right.

If slope is negative, the  line falls from left to right.

A zero slope is slope of horizontal line.

A undefined slope is slope of vertical line.

Slope of the given line is 5.

Hence, slope is positive. It means the graph of the line start from the left and goes toward the right.

Hence , choice A is correct answer.

QUESTION A

The given points are

(x_1,y_1)=(8,3) and (x_2,y_2)=(9,8)

The slope can be found using the formula;

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

We substitute the point to obtain;

m=\frac{8-3}{9-8}

This simplifies to

m=\frac{5}{1} =5

Therefore the slope is 5.

QUESTION 2

A positive slope indicates a rising line

A negative slope indicates a rising line

A zero slope means the line is horizontal.

An undefined slope means the line is vertical.

The correct answer is

A. The line rises from left to right.

The arch of a bridge forms the upper half of an ellipse. The arch is 6 meters above the 20-meter-wide river. Write an equation f
aksik [14]

Answer:

\frac{x^2}{36} + \frac{y^2}{100} = 1

Step-by-step explanation:

Required

The equation of the ellipse

This is calculated as:

\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1

Where:

b =6 ---- height

a = 0.5 * 20 =10 --- width

So:

\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1

\frac{x^2}{6^2} + \frac{y^2}{10^2} = 1

\frac{x^2}{36} + \frac{y^2}{100} = 1

After 5 tests Dara's average score was 88 what score must she average on the next two tests to have a seven-test average of 90?
Tomtit [17]

After 5 tests, her average was 88. To have a seven-test average of 90, the total must be:

90 \times 7 = 630

Her average after 5 tests was 88. Her total score on the 5 tests is:

88 \times 5 = 440

Subtract:

630-440 = 190

Find the average by dividing by 2:

190 \div 2 = 95

Her average must be 95
