Question

find equation of line passing through
two points (1, 2) and (4,7)​

Answer 1

Answer:

ANSWER

Since slope of line passing through two points (x

​

,y

​

) and (x

​

,y

​

) is m=

x

​

−x

​

y

​

−y

We now find the slope of the line passing through the points (7,5) and (−9,5) as shown below:

m=

−9−7

5−5

​

=

−16

0

​

=0

Therefore, the slope of the line is 0.

Now use the slope and either of the two points to find the y-intercept.

y=mx+b

5=(0)(7)+b

b=5

Write the equation in slope intercept form as:

y=mx+b

y=(0)x+5

y=5

Hence, the equation of the line is y=5.

Answer 2

Step-by-step explanation:

(y-2)=(7-2)/(4-1) (x-1)

y-2=5/3(x-1)

3y-6=5x-5

5x-3y+1=
