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

Answer 1

Eli Assouline

Below

When plotting points, you just need to find the x and y intercepts

When #y=0#, #0=2x+5# #x=-5/2# #(-5/2,0)#

When #x=0#, #y=0+5# #y=5# #(0,5)#

Plot your two points on the graph and join them together graph{2x+5 [-10, 10, -5, 5]}

To graph the equation y = 2x + 5 by plotting points:

Choose several values of x.
Substitute each value of x into the equation to find the corresponding y-values.
Plot each pair of (x, y) points on the coordinate plane.
Draw a line passing through the plotted points to represent the graph of the equation.

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.
