How do you graph #y= -2x + 5# by plotting points?

Answer 1

Julia Adams

Assign values to x to calculate y

If x is 0, #y=5#

If x is 1, #y=3#

If x is 2, #y=1#

The graph of the linear function is as follows:

graph{–2x + 5 [–2.52, 7.48, 9.79, -10.21]}

To graph the equation ( y = -2x + 5 ) by plotting points, you can choose values for ( x ), calculate the corresponding ( y ) values using the equation, and then plot the points on a coordinate plane.

Let's choose three values for ( x ) to start:

When ( x = 0 ): ( y = -2(0) + 5 = 5 ) So, the point (0, 5) is on the graph.
When ( x = 1 ): ( y = -2(1) + 5 = -2 + 5 = 3 ) So, the point (1, 3) is on the graph.
When ( x = -1 ): ( y = -2(-1) + 5 = 2 + 5 = 7 ) So, the point (-1, 7) is on the graph.

Now, 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.
