Q:
# Type the correct answer in each box.Use numerals instead of words. If necessary, use / for the fraction bar.Line AB and Line BC form a right angle at their point of intersection, B.If the coordinates of A and B are (14, -1) and (2, 1), respectively, the y-intercept of Line AB is _____ and the equation of is y = ___x+___.If the y-coordinate of point C is 13, its x-coordinate is ___.

Accepted Solution

A:

Answer:y intercept is 1 1/3equation is y = -1/6x + 4/3x coordinate is -70 (-70,13)Step-by-step explanation:find Mm = 1 - (-1)/ 2 -1 4m = -2/12 = -1/6Find y intercept--Plug m and one point from above into y = mx + b1 = - 1/6 (2) + b1 = -2/6 + b1 2/6 = b1 1/3 = b4/3 = bTo find the x coordinate if y is 1313 = -1/6 x + 4/311 2/3 = -1/6 x-70 = x
