y=97x+237

Explanation:

We are given two points : -

(6,11),(1,2) .... Points

Let, x1=6andy1=11

Let, x2=1andy2=2

Hence, the two points given to us can be written as

(x1,y1),(x2,y2) .... Points

We will next find the Slope using the formula:

Slope(m)=y2y1x2x1

Slope(m)=21116

97=97

Therefore,

Slope(m)=97

The Point-Slope Equation of a Straight Line is given by:-

(yy1)=m(xx1) Formula.1

We can substitute the value of Slope(m)=97 in the equation above.

We also need a Point.

We will choose one the points given to us: (6,11)

This point (6,11) is our (x1,y1).

We are ready to use the Point-Slope Equation of a Straight Line using Formula.1

Substitute the values of m and (x1,y1).

y11=97(x6)

y11=97x547

y=97x+237

Hence, the Equation of a Straight Line passing through the points (6,11),(1,2) is given by:-

y=97x+237

Graph below has the equation of the straight line we found:
