If anyone knows this can you i have about an hour left to submit this (:

find the area of a triangle with the given vertices.

part i: graph the following points on the coordinate grid below.
(1, -3), (3, -1), (5, -3)

part ii: find the area of the triangle. show your work.

Part 1 : Figure show the graph of triangle

Part 2 : The area of triangle is 4 sqaure units

Step-by-step explanation:

Given points A(1, -3), B(3, -1) and C(5, -3) make triangle.

Part 1:

Figure show the graph of triangle with A(1, -3), B(3, -1) and C(5, -3)  as vertices.

Part 2: Find the area of the triangle.

The area of triangle is given by A=

From figure, Take base as length of AC

Length of line is given by L=

Now, Base = length of AC

Base =

        =

        =

        =

        =4units

and Height as difference of y-component of point A and point B

Height = (y of component of point B)- (y of component of point A)

           = (-1)- (-3)

           = 2units

Therefore, The area of triangle is given by A=

A=

A=4 sqaure units

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
