Question
Find a number $t$ such that the line in the $x y$ plane containing the points $(t, 4)$ and (2,-1) is perpendicular to the line $y=6 x-7$.
Step 1
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula: m = (y2 - y1) / (x2 - x1) In this case, (x1, y1) = (t, 4) and (x2, y2) = (2, -1). So, the slope of the line is: m = (-1 - 4) / (2 - t) = -5 / (2 - t) Show more…
