-7x > -42. So you divide on both sides by -7 and that gives you x > 6
Since the slope is -2 because
x1: -1 x2: 0
y1: 2 y2: 0
y2-y1/x2-x1 = slope (0-2/0+1= -2/1 = -2)
You would havr to change it into point slope form so it would look like this
Y-2 = -2(x+1)
y-2 = -2x -2
+2 +2
y = -2x + 0
Hope this helps:)
I think it's need to be a graph right?
Let, the price of jacket before tax = x
it would be: x*105/100 = 118.65
x = 11865/105
x = $113
