Slope, found using the points is -55/11 = -5 We use that for the equation y=mx+b where m=-5. Since we also know one of the points, we can plug that in and find b -12=-5(4)+b -12=-20+b 8=b
2m+5=5(m-7)-3m first, use distributive property... 2m+5=5m-35-3m next, combine like terms on the right side... 2m+5=2m-35 next, subtract 2m from both sides. 2m+5=2m-35 -2m -2m you will get.... 5=-35 in which is not true. This means the equation has no solution.
