Answer:

Step-by-step explanation:
I'll start by finding the slope of this line using the slope formula:

Just by looking at the graph I know that the y-intercept is 20, so now I can write the equation in slope-intercept form (y=mx+b):

The altitude of a triangle is a line segment through a vertex and perpendicular to a line containing the side opposite the vertex.
Answer: 
Answer: Give me an example
Step-by-step explanation:
Answer: D- 97.4
Step-by-step explanation:
For the scale factor of 1:3. Use ratio and proportion to solve for the area of the triangle.
area of triangle RST/ area of triangle XYZ = (1/3)^2
where
area of traianlge RST = 10.825 inch^2
Area of triangle XYZ= Area of triangle RST x (3)^2
Substitute the given values=97.4 inch^2
