Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that? 3 x minus 2 y = 6. 0.4 (20 y + 15) = x. y = negative three-halves x + 3 y = one-eighth x minus three-fourths y = three-halves x minus 3 y = one-eighth x minus three-fourths y = negative three-halves x minus 3 y = one-fifth x minus StartFraction 15 Over 4 EndFraction y = three-halves x minus 3 y = one-fifth x minus StartFraction 15 Over 4 EndFraction
