Graph y equals 2x plus 3?

Answer 1

-1

Answer 2

2x+y=-3 is the same as y=-3-2x

This is a straight line that slopes downward with a slope of -2 and intercepts the y-axis at y=-3

Its graph will be a straight line that intersects the y-axis at y=-3 and slopes upward to the left and downward to the right at a relatively steep angle. If you have graph paper, when going to the left of the y-intercept it will rise two boxes for every one box that it goes horizontally. Similarly, going to the right of the y-intercept it will fall two boxes for every one box it travels horizontally.

Answer 3

When x is zero, y is 3, so plot that point.

When x is one, y is 5, so plot that point.

Now draw a straight line between those two points.
