Find the slope (m) and y - intercept (c) of the line y = -x.
m = -1, c = -1
m = -1, c = 1
m = 0, c = -1
m = -1, c = 0
The equation of the line is y = -x
Comparing with y = mx + c we get m = -1 and c = 0
Hence (D)
Find the slope (m) and the y-intercept (c) of the line x+y+5=0.
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
If three lines whose equations are y=m1x+c1, y=m2x+c2 and y=m3x+c3 are concurrent, then show that m1(c−2−c3)+m2(c3−c1+m3(c1−c2)=0.
