Question 1002994
7y+42=-14x
7y=-14x+42
y=-2x+6
=====
-y=-7x+32
y=7x-32
====Isolate the y, and then make it +1 by dividing both sides by the coefficient, 7 at the top, -1 at the bottom.
=======
-3x-3=y
The intercept is (0,-3).  The slope is -3. It goes down and to the right, moving right 1 unit and down 3 or moving left 1 unit and up three.======
y=x+1
the y intercept is (0,1).  The graph goes right 1 and up one unit or left one unit and down 1 unit.
{{{graph(300,200,-10,10,-10,10,-3x-3,x+1)}}}
The number is the y-intercept.
The coefficient of x is the slope
