Question 1063879

A little stuck here: find the value of x or y so that the line through the points has the given slope.

(x,11) and (4,-14); slope: undefined

thank you :)
<pre>An UNDEFINED slope means that the DENOMINATOR in the slope equation: {{{matrix(1,3, m, "=", (y[1] - y[2])/(x[1] - x[2]))}}} equals 0.
Therefore, we set the denominator equal to 0, and get: 4 - x = 0
- x = - 4
{{{highlight_green(x = (- 4)/(- 1) = 4)}}}
