CCSS.8.F.A.3

The equation y=3x - 5 is in slope-intercept form y=mx+b.

So, we can graph this line by FIRST graphing the ....

• "b" the y-intercept,

  by placing a dot on the y-axis at -5 then use the slope, up 3 over 1.

• start at (0,0) and then graph the "m" the slope up 3 over 1.

• pick a random spot on the graph and use the slope up 3 over -5.

• graph the coordinate (3, -5) then draw a line

What is 'b' in this linear equation? y= 5x - 6

• 6

• 5

• y

• -6
