Enter the slope-intercept equation for the image of line ℓ after a clockwise rotation of 90°. (Hint: To find the image of line ℓ
Marat540 [252]

Answer:

y=\frac{1}{7}x-\frac{6}{7}

Step-by-step explanation:

Two points (1, -1) and (0, 6) are lying on the given line.

Rule to find the coordinates of a point by the rotation of 90° clockwise is,

(x, y) → (y, -x)

Therefore, image points of (1, -1) and (0, 6) will be,

(1, -1) → (-1, -1)

(0, 6) → (6, 0)

Slope of the line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

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

Therefore, slope of the line passing through (-1, -1) and (6, 0) will be,

m = \frac{0+1}{6+1} = \frac{1}{7}

Equation of the line passing through (6, 0) and slope = \frac{1}{7}

y - y' = m(x - x')

y - 0 = \frac{1}{7}(x - 6)

y=\frac{1}{7}x-\frac{6}{7}

How many 1/3s are in 1 2/3 the hexagon represents 1 whole
Vikki [24]

We need to find, how many 1/3s are in 1 2/3 the hexagon represents 1 whole.

In order to find that value, we need to divide 1 2/3 by 1/3.

Let us first convert 1 2/3 into improper fraction first.

1 2/3 = (1*3+2)/3 = 5/3.

Therefore,

5/3 ÷ 1/3.

Changing division sign into multiplication and flipping the second fraction, we get

5/3 × 3/1

3's cross out from top and bottom, we get

= 5.

<h3>Therefore, there are 5 times of 1/3s in 1 2/3.</h3>
