Question

Indicate in standard form the equation of the line passing through the given points.

B(0, 0), C(4, -4)

(I know y'all are not suppose to just give me the answers but I have an hour to finish an online class that I'm 80%. So if someone could be a pal

Answer 1

first we find the slope
(0,0)(4,-4)
slope = (y2 - y1) / (x2 - x1)
slope = (-4 - 0) / (4 - 0)
slope = -4/4 = -1

y = mx + b
slope(m) = -1
(4,-4)...x = 4 and y = -4
now we sub...we r looking for b, the y intercept
-4 = -1(4) + b
-4 = -4 + b
-4 + 4 = b
0 = b

so your equation is : y = -1x + 0....or y = -x
