Y= 3x - 4
2x + y = 1

when graphed in the xy-plane, the lines described by the equations above each include a diameter of a circle. if the circle includes the point (-2, -5), which of the following is the equation of the circle?

and explain.

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas
