Answer:

Option B

Step-by-step explanation:

Slope of the line is calculated by the formula:

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

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\$

so the slope(m) equals -9/5

A rectangular prism. The rectangular base has a length of 5 centimeters and width of 4 centimeters. What are the dimensions of t

AVprozaik [17]

Answer:

dimension is 5cm * 4 cm

Step-by-step explanation:

As the plane is parallel to the base, the ratio between plane's length and width is equal to the ratio of that of the base. -> similar shape.

Moreover, it also divided the rectangular prism into 2 smaller rectangular prism. hence the plane is identical to the base. Hence, same dimension.

Find the distance between each pair of points. Round to the nearest tenth<br> (-2,2) (5,2)

bija089 [108]

Answer:

Distance = 7

Step-by-step explanation:

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(5-(-2))^2+(2-2)^2} \\d= \sqrt{(7)^2+(0)^2} \\d= \sqrt{49+0} \\d= \sqrt{49}\\ d= 7$
