Dominique needs to solve the system of equations by graphing. Which statement is true about the system? 2 x minus 3 y = 12. y = negative three-fifths x + 2. Both equations are in slope-intercept form. Neither equation is in slope-intercept form. The first equation is y = two-thirds x minus 4 when written in slope-intercept form. The second equation is 3 x + 5 y = 10 when written in slope-intercept form.
