Question

Graph y=2x+3 Pls give me an explanation while u answer

Answer 1

Functions like these are just mattress of plugging in.

Graph: y = 2x+3

Let's just take five numbers: -2, -1, 0, 1, 2

Make a table like the disclosed image, but replace the function at the top-middle with:

y = 2x + 3

Go through each equation by replacing the 'x' in each equation with the given number.

Example:

Number: -2

Function: y = 2x + 3

Plug-in: y = 2(-2) + 3

Simplify: y = -4 + 3

Simplify: y = -1

Repeat this with -1, 0, 1, and 2 to draw the function.
