11. MARINE BIOLOGY Killer whales usually swim at a rate of 3.2-9.7 kilometers per hour, though they can travel up to 48.4 kilometers per hour
Suppose a migrating killer whale is swimming at an average rate of 4.5
kilometers per hour. The distance d the whale has traveled in t hours can b
predicted by the equation d = 4.51.
a. Graph the equation.
b. Use the graph to predict the time it takes the killer whale to travel 30
kilometers.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
