Find the slope of (5,-5) and (-4,5)

Answers

Answer 1
Answer:

Answer:

Slope of points (5,-5) and (-4,5) is \mathbf{-(10)/(9) }

Step-by-step explanation:

We need to find the slope of points (5,-5) and (-4,5)

The formula used to find slope is: Slope=(y_2-y_1)/(x_2-x_1)

We have x_1=5, y_1=-5, x_2=-4 \ and \ y=5

Putting values in formula and finding slope

Slope=(y_2-y_1)/(x_2-x_1)

Slope=(5-(-5))/(-4-(5))\nSlope=(5+5)/(-4-5)\nSlope=(10)/(-9)\nSlope=-(10)/(9)

So, slope of points (5,-5) and (-4,5) is \mathbf{-(10)/(9) }

Find the area of the combined figure. A figure is made up of a triangle and a rectangle. The triangle has a height of 8.5 inches and a base of 10 inches. The rectangle has dimensions of 9 inches x 10 inches. What is the area of the figure? a 102.5 square inches b 132.5 square inches C 110.2 square inches d 140.2 square inches​

Answers

Answer:

132.5

Step-by-step explanation:

for the triangle 8.5 * 10 / 2 = 42.5

the rectangle 9 * 10 = 90

42.5 + 90 = 132.5

PLEASE I Can’t figure this out. Write the slope-intercept form of the line that travels through (4,-1) and is parallel to y = 1/4x

Answers

Answer:

y = 1/4x - 2

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is y = 1/4x. Its slope is 1/4. A line parallel to this one will also have a slope of 1/4.

Plug this value (1/4) into your standard point-slope equation of y = mx + b.

y = 1/4x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -1). Plug in the x and y values into the x and y of the standard equation.

-1 = 1/4(4) + b

To find b, multiply the slope and the input of x (4)

-1 = 1 + b

Now, subtract 1 from both sides to isolate b.

-2 = b

Plug this into your standard equation.

y = 1/4x - 2

This equation is parallel to your given equation (y = 1/4x) and contains point (4, -1)

Hope this helps!
