Answer: y+7x=499

Step-by-step explanation:

The equation of a line  passes through the points (a,b) and (c,d) is given by :-

(y-b)=\frac{d-b}{c-a}(x-a)

Hence, the equation of a line  passes through the points (7, 450) and (14, 401) is given by :-

(y-450)=\frac{401-450}{14-7}(x-7)\\\\\Rightarrow y-450=\frac{-49}{7}(x-7)\\\\\Rightarrow y-450=-7x+49\\\\\Rightarrow y+7x=49+450\\\\\Rightarrow y+7x=499

Find the equation of the line. <br> Please need help badly!!
hoa [83]

Answer:

lets consider two end points are the marked points ,

Then ,

(1,5)=x1,y1

(-1,-3)=x2,y2

line passes through point(1,0)=x3,y3

slope of line ,m = (y2-y1)/(x2-x1)

= (-3-5)/(-1-1)

=4

Eqn of line is:

y-y3=m(x-x3)

y-0 = 4(x-1)

y=4x-4

4x-y=4 is reqyuired eqn..

Step-by-step explanation:

Problem may arise due to calculation but plz check it ...
