QuestionFind xx so that the line through (x,3)(x, 3) and (5,9)(5, 9) has a horizontal slope.

Studdy Solution

STEP 1

Assumptions1. The line passes through the points (x,3)(x,3) and (5,9)(5,9). . The line has a horizontal slope.

STEP 2

The slope of a line passing through two points (x1,y1)(x1, y1) and (x2,y2)(x2, y2) is given by the formulalope=y2y1x2x1lope = \frac{y2 - y1}{x2 - x1}

STEP 3

We know that the slope of a horizontal line is0. So, we can set up the equation for the slope of the line passing through the points (x,3)(x,3) and (5,9)(5,9) and set it equal to0.
0=935x0 = \frac{9 -3}{5 - x}

STEP 4

olve the equation for xx.
0=6x0 = \frac{6}{ - x}

STEP 5

To solve for xx, we can multiply both sides of the equation by (5x)(5 - x) to get rid of the fraction.
0=0 =

STEP 6

This equation is not possible, as0 cannot equal6. Therefore, there is no value of xx that will make the line passing through the points (x,3)(x,3) and (5,9)(5,9) have a horizontal slope.
There is no solution for xx.
