Question

Here is an equation.-2=6-2xDraw a graph to help solve the equation. Then find the solution to the equation.Is what I did a correct step?

Answer 1

we have the equation

-2=6-2x

this is the equation of a vertical line

wee need two points to draw the line

so

For x=4

-2=6-2(4)

-2=6-8

-2=-2 -----> is true

that means

x=4 is a solution of the equation

graph the equation

x=4

see the attached figure
