Question

Please help, i need to know the steps of solving this question

Answer 1

Answer:

Step-by-step explanation:

eq. of line through (-4,0) and (3,2) is

y-0=(2-0)/(3+4) (x+4)

y=2/7 (x+4)

or y=2/7 x+8/7

m1=2/7

b1=8/7

eq. of line through (-3,2) and (4,0) is

y-2=(0-2)/(4+3) (x+3)

y-2=-2/7(x+3)

y=-2/7 x-6/7 +2

or y=-2/7 x+8/7

m2=-2/7

b2=8/7

m1b2+m2b1

$=\frac{2}{7} \times \frac{8}{7} +(-\frac{2}{7} ) \times \frac{8}{7} \\=\frac{16}{49} -\frac{16}{49} \\=0$
