Graphing lines in y=mx+b

Question 1: When graphing the equation of a line, we want to get it into what form before graphing?

Question 2: When graphing an equation in the form of y=mx+b,

Question 3: When graphing the equation y=4x-6

we start at -6 on the y-axis then plot another point up 4 and left 1 on the coordinate plane.
we start at -6 on the y-axis then plot another point up 4 and right 1 on the coordinate plane.
we start at 4 on the y-axis then plot another point down 6 and right 1 on the coordinate plane
we start at -6 on the x-axis then plot another point up 4 and right 1 on the coordinate plane

Question 4: Write the y-intercept and slope of the graph shown below

Question 5: How would you graph 6x-3y=21?

solve the equation for y; y=2x+7, start at 7 on the y-axis, go up 2 and right 1
solve the equation for y; y=2x-7, start at -7 on the y-axis, go up 2 and right 1
solve the equation for y; y=2x-7, start at 7 on the y-axis, go up 2 and right 1
solve the equation for y; y=.5x-7, start at -7 on the y-axis, go up 1 and right 2
