Question

OS 11.9 (a) 5X + OVC (c) At - 7 - 21 (e) Vmx + 5 (0) Ax + By = 0 the characterizing property for each family of lines. (1) ] = f Lan 50° + b live x-intercep(2.0) • (b) 6x + By = 24 (d) y = 4x + b (1) kx + kyk (h) m(x + 2) = y- (1) x=4

Answer 1

Family of lines characteristics

b) 6x + By = 24

find x-intercept

24/6 = 4. = C/A

y= 0

Then ANSWER IS

x- intercept= (4,0)

2nd part

c) Ax - 7y= 21

Find y- intercept

C/B= 21/-7 = -3

Also

x=0

Then. ANSWER IS

y-intercept is = ( 0,-3)
