NEED HELP ASAP, IM BEING TIMED! Antoinette needs to solve this system by graphing. Which statements explain how she should graph the equations? Check all that apply.
2x-7y=56
y=-2.5x+4

A. she should rewrite both equations in slope-intercept form.
B. she should rewrite the first equation in slope-intercept form.
C. she should find that the second equation has a slope of 4.
D. When rewinding the first equation, she should subtract 2x from each side of the equation to get-7y by itself.
E. After rewriting the first equation in slope-intercept form, she should find that both lines have negative slopes.
