<span>So what we need to do is to use the formula that works perfectly is this one: Base area=2b^2 so when we replace the data, then we can have: Vol=1/3h2b^2=(2hb^2) / 3 Hope it is good for you</span>
From looking at the graph, we can already tell it's a negative slope because it's tilting down, so we can eliminate A and D. Where the line intersects the y-axis is the y-intercept or b. Since it intersects at (0,2), the equation should be y=-2x+2.
