How do you graph #y=-2x+3# by plotting points?

Answer 1

see explanation.

Select any value for x and enter it into the equation to find the matching value for y.

#x=0toy=0+3to(0,3)larrcolor(red)" y-intercept"#
#x=-2toy=4+3=7to(-2,7)#
#x=2toy=-4+3=-1to(2,-1)#

The graph is generated by plotting these three coordinate points: graph{-2x+3 [-10, 10, -5, 5]}

Answer 2

To graph the equation y = -2x + 3 by plotting points, follow these steps:

  1. Choose a set of values for x. For example, you can choose x = -2, -1, 0, 1, and 2.
  2. Substitute each value of x into the equation to find the corresponding y-coordinate.
  3. Plot the points (x, y) on a coordinate plane.
  4. Connect the points with a straight line.

For x = -2: y = -2(-2) + 3 = 4 + 3 = 7, so the point is (-2, 7).

For x = -1: y = -2(-1) + 3 = 2 + 3 = 5, so the point is (-1, 5).

For x = 0: y = -2(0) + 3 = 0 + 3 = 3, so the point is (0, 3).

For x = 1: y = -2(1) + 3 = -2 + 3 = 1, so the point is (1, 1).

For x = 2: y = -2(2) + 3 = -4 + 3 = -1, so the point is (2, -1).

Plot these points on a coordinate plane and connect them with a straight line.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
