Answer:  The correct option is

(D) rotation of 270 degrees counterclockwise and shifting 3 units up.

Step-by-step explanation:  We are given to select the correct transformations that were applied to triangle ABC to obtain triangle A'B'C'.

From the graph, we note that

the co-ordinates of the vertices of triangle ABC are A(3, 4). B(5, 6) and C(8, 1).

And, the co-ordinates of the vertices of triangle A'B'C' are A'(4, 0), B'(6, -2) and C'(1, -5).

We see that

if a point (x, y) is rotated 270 degrees counterclockwise and then shifted 3 units up, then its co-ordinates becomes

(x, y)   ⇒   (y, -x+3).

With this transformation rule,

A(3, 4)  ⇒  (4, -3+3) = (4, 0),

B(5, 6)  ⇒  (6, -5+3) = (6, -2)

and

C(8, 1)  ⇒  (1, -8+3) = (1, -5).

Since the resulting co-ordinates are the vertices of triangle A'B'C', so the required transformations rare

rotation of 270 degrees counterclockwise and shifting 3 units up.

Option (D) is CORRECT.

Which graph represents a proportional relationship
vodomira [7]

Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

ollegr [7]

Answer:

Step-by-step explanation:

A(3, - 2), B(1, 5), C(1, - 2)

ΔABC is right angled Δ

AC and BC are legs (cathetus)

A_{ABC} = (AC)(BC) ÷ 2 = \frac{2*7}{2} = 7 units²

Complete the equation of the line whose slope is 5 and y intercept is (0,4)
irina1246 [14]

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)

<em><u>Solution:</u></em>

Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ---- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, slope = m = 5

y intercept is (0, 4)

So, c = 4

<em><u>Substitute c = 4 and m = 5 in eqn 1</u></em>

y = 5x + 4

Thus the equation of line is found
