Ответ:
y = x + 1
step-by-step explanation:
slope-intercept form : y = mx + b
where m is slope and b is the y-intercept
the side of triangle abc perpendicular to segment ef is the segment bc. (also shown in the figure how the projected lines are perpendicular to each other)
point b : (4,5)
point c : (1,2)
slope is calculated as: (y2-y1)/(x2-x1)
it doesnt matter which point is 1 or 2. taking b as 2 and c as 1:
slope = (5-2)/(4-1) = 3/3 = 1
y-intercept is clearly shown in the figure: 1
equation in slope-intercept form:
y = x + 1
