Answer:

y=-3x+4

Step-by-step explanation:

1. Use the saying "rise over run" to find the slope. Starting at the highest dot, we can count down 3 and across 1. This means the slope is -3/1 or -3.

2. After finding the slope, we need to find the y-intercept. Locate where the line crosses the y-axis, in this case it is at 4.

3. Finally, plug in these numbers to the slope intercept format: y=mx+b. 'm' is the slope and 'b' is the y-intercept.

Which of the points shown below are on the line given by the equation y = x?

mr_godi [17]

Answer:

point D

Step-by-step explanation:

think about it....y = x.....this is saying that x and y are equal

now look at point D. (-3,-3)...x = -3 and y = -3

therefore, y = x

the rest of them dont work

because on A, 1 does not equal -1

because on B, 4 does not equal 2

because on C, -3 does not equal 3

If PQRS is a rectangle, find the length of QT

MAVERICK [17]

Step-by-step explanation:

Since, opposite sides of a rectangle are equal and each angle is of 90°.

$\therefore$ QP = RS = 14 cm

$In \:\triangle QPS, \: \angle QPS = 90\degree$

$\therefore \: QS= \sqrt{QP^2+ PS^2} \\ \therefore \: QS= \sqrt{(14)^2+ (20)^2 } \\ \therefore \: QS= \sqrt{196 + 400} \\ \therefore \: QS= \sqrt{596} \\ \therefore \: QS= 24.41 \: m$

$\because$ Diagonals of a rectangle bisects each other.

$\therefore\: QT = \frac{1}{2} QS\\\therefore\: QT = \frac{1}{2} \times 24.41\\\therefore\: QT =12.205\\\huge\orange {\boxed {\therefore\: QT =12.21\:m}}$
