Answer:
To find the equation of the altitude from point A to side BC, we can use the formula for the equation of a line in point-slope form, which is:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line.
We can find the slope of the line by using the formula for the slope of a line between two points:
m = (y2 - y1)/(x2 - x1)
We can use this formula to find the slope of line BC, which is the line connecting points B and C. Substituting the coordinates of these points into the formula gives us:
m = (2 - (-2))/(2 - 6) = 4/-4 = -1
Next, we can use the point-slope form of the equation of a line to find the equation of the altitude from point A to line BC. Substituting the coordinates of point A and the slope of line BC into the point-slope formula gives us:
y - 1 = -1(x + 2)
This is the equation of the altitude from point A to line BC.
