Find the slope (m) and the y-intercept (c) of the line x+y+5=0.
m = 1, c = 5
m = -1, c = -5
m = -1, c = 5
m = 1, c = -5
The given equation is x+y+5=0
Thus , y=−x−5
Comparing with y=mx+c we get
m=−1, c=−5
Find the slope (m) and y - intercept (c) of the line y = -x.
Find the slope (m) and y - intercept (c) of the line y=4x−12.
If the three lines y=m1x+c1,y=m2x+c2 and y=m3x+c3 are concurrent then show that,
m1(c2−c3)+m2(c3−c1)+m3(c1−c2)=0
