Question

Which is an equation of the given line in standard form?

A.
–8x + 9y = 23

B.
–8x + 9y = –23

C.
–8x + 7y = 25

D.
–9x + 8y = –23

Answer 1

we have two points so we can calculate the slope:
m=(3+1)/(1/2+4)
m=8/9
then use one of point and write the equation with the slope:
y+y1=m(x+x1)
so
y+1=8/9(x+4)
