FranChoose a value for x, say, x=1. Then for that x, you have y=3 times 1, then minus 3, which is 0. Put a dot on the graph at the place which is lined up with x=1 and y=0. Choose another x, and work out what is y and put another dot. Do it for more values. Finally draw a line which is smooth (no kinks) that join up the dots. In this case it should turn out to be a straight line.

How do you graph y-3x-3?
y-3x-3 y=3x+3 A line with a slope of 3 crossing the y-axis at 3.
What kind of graph represents 3x plus y equals negative 1?
3x + y = -1 y = -3x - 1 The graph is a straight line, with a slope of -3, passing through the point Y = -1 on the y-axis.
Graph y equals 3x - 7 what is the y intercept?
-7
How yo solve y equals 3x when x equals 6 and give ordered pair that would be plotted on a graph?
y = 3x =3(6) = 18 ... the ordered pair is (x,y) = (6,18)
What is the slope of the graph of 3x plus y equals 7?
3x + y = 7 First, turn the equation into the slope-intercept form, y = mx + b, where m is the slope of the graph that that equation represents (solve for y).3x + y = 7 subtract 3x to both sidesy = -3x + 7So you clearly see that the slope is -3.
