Chris is making a pennant in a shape of a triangle for his senior class photo. He wants the base of this triangle to be 4 inches. The area of the pennant must be 16 square inches

The formula for finding the area of a triangle 1/2 base * height. This time, we know the base and the area, so we have to find the height. Let's say the variable h represents height. 1/2 (4) * h = 16. 2 * h = 16. If you divide both sides of the equation by 2, you get h = 8. Therefore, the height of the triangle must be 8 inches with a base of 4 inches to get an area of 16 square inches. You can double check by doing: 1/2 (4) * 8 = 16. To check if its correct, solve it to get 2 * 8 is 16, which is accurate.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
