there is always a y-intercept in all graphs.
be it a line graph, quadratic graph or cubic graph. all graphs will definitely have a y-intercept. and in this case, since y=mx + c where c is the y-intercept. the y intercept of this graph is 10
first i plotted all my points on a grid graph
i made sure all of them were in the correct quadrant
then i saw it was a trapezoid or a quadrilateral
the answer is c.
