Question

How would you graph the solution to -5w + 9 = 14 on a number line?

1) Draw a point one unit to the right of zero.
2) Draw a point five units to the right of zero.
3) Draw a point five units to the left of zero.
4) Draw a point one unit to the left of zero.

Answer 1

Draw a point one unit to the left of zero.

Explanation:

The equation of unknown w is given here and we have to solve it and then we have to check how to draw the point w on the number line.

Now, the equation is - 5w + 9 = 14

⇒ - 5w = 5

⇒ w = - 1

Now, we know that in a number line if we move right from zero then this is a positive direction and if we move left from zero then this direction is the negative direction.

Hence, to plot w = - 1, we must draw a point one unit to the left of zero. (Answer)
