you can use the points given to find the slope of the line which is 1. you can apply the slope to then find the y-intercept which is 4. so when you put this information in slope intercept form it would be: b = a + 4 or answer C
If 16 corn muffins takes 1 cup of flour, 40 corn muffins can be made because 16 x 2=32 and half of 16 is 8, 8+32=40. So, 40 corn muffins can be made out of 2 1/2 cups of flour.
