What is the equation of a line through (-1, 4) and (-2, 7)?Question 27Select one:a.y = 3x + 1b.y = -3x + 1c.y = -3x + 7d.y = 3x + 7e.None of these
Question
Solution 1
To find the equation of a line through two points, we can use the formula for the slope of a line, which is (y2 - y1) / (x2 - x1).
First, let's find the slope (m) using the given points (-1, 4) and (-2, 7):
m = (7 - 4) / (-2 - (-1)) = 3 / -1 = -3
So, the slope of the line is -3.
