Question
Find a number $t$ such that the line containing the points $(t,-2)$ and (-3,5) is perpendicular to the line that contains the points (4,7) and (1,11)
Step 1
The slope of a line containing points (x1, y1) and (x2, y2) is given by the formula: m = (y2 - y1) / (x2 - x1) So, the slope of the line containing the points (t, -2) and (-3, 5) is: m1 = (5 - (-2)) / (-3 - t) m1 = 7 / (-3 - t) Show more…
