C is on the x axis
Answer:
slope= -3
y-intercept= 6
Step-by-step explanation:
1. Approach
To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.
2.Solve for the slope
The formula to find the slope of a line is;

Where (m) is the variable used to represent the slope.
Use the first two given points, and solve;
(1, 3), (2, 0)
Substitute in,

Simplify;

3. Put equation into slope-intercept form
The equation of a line in slope-intercept form is;

Where (m) is the slope, and (b) is the y-intercept.
Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).

Substitute in point (3, -3)

Answer:
Option C. 6 square units
Step-by-step explanation:
we know that
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let
a,b,c be the lengths of the sides of a triangle.
The area is given by:

where
p is half the perimeter
p=
we have
Triangle ABC has vertices at A(-2,1), B(-2,-3), and C(1,-2)
the formula to calculate the distance between two points is equal to

step 1
Find the distance AB



step 2
Find the distance BC



step 3
Find the distance AC



step 4



Find the half perimeter p
p=
Find the area
