Formula for triangle area = base times height over two. area of smallest triangle: 2*2/2, so 2. area of medium sized triangle: 2*6/2, so 6. the square in between those triangles has an area of four (2*2). the base of the largest triangle is 2+2+6, so 10, and the height is 4. use the formula to find its area is 20. add them all together to get 4+6+4+20 is 34 units^2.

Slope intercept is y=Mx+b where m is always the slope and b is always your y intercept. The point slope fo is y-y^1=m(x-x^1) where x1 and y1 are a known point and m is the still the slope. X and y is another point on the linear equation
