Question

19. Find the equation of a straight the passing through
(5-3) and (7-4)​

Answer 1

Answer:

ANSWER

Let us take the line in slope-intercept form, which is y=mx+c ........... (i)

It passes through the point P(−2,−3) and slope m=

5

3

If a line passes through point P(p,q) and slope m=a, then the value of c can be obtained by putting

x=p,y=q and m=a

Here, p=−2,q=−3 and m=

3

Substituting x=p=−2,y=q=−3 and m=a=

3

in (i) we get

−3=

−9

∴(i) becomes y=

−9

⟹3x−5y−9=0

Hence, option B is correct.
