Question

Find the equation of a line through the points (7,-3)and(2,-2).if this line meets x axis at Pand y axis at Q;find coordinates of p and q

Answer 1

eq of line is in the form of

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

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

m=-1/5

eq,

y-(-3)= (-1/5)(x-7)

y+3= -x/5+7/5

5y+15= -x+7

x+5y+15-7=0

x+5y+8=0
