The answer is D. y = -2x + 20. This is because it has a negative slope (-2x). When a number in a slope-intercept equation has the variable (x), that determines the positive or negative association. If it is a positive slope, it travels up from left to right. If it is a negative slope, it travels down from left to right.
Hi so imagine a tent... It looks like a pyramid right?
Well when its asking for a tent flap, its talking about one triangle of the pyramid.
So its asking you to find the area of one triangle of the pyramid.
Does this make sense??
So the formula for an area of a triangle is (b*h)/2
So the answer is multiply the two numbers together then divide by 2.
Does this make sense?
