What is the equation of the graphed linear model?
y =
x +
scatter plot on a first quadrant coordinate grid. the horizontal axis is labeled variable m. the vertical axis is labeled variable n. points are plotted at (zero, one hundred), (five, one hundred ten), (ten, eighty), (fifteen, fifty), (twenty, seventy), (twenty, one hundred), (twenty-five, sixty), (thirty, twenty), (thirty, seventy-five), (thirty-five, sixty-five), (forty, forty), (forty-five, ten). a line is drawn through (twenty, seventy) and (twenty-five, sixty).

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
