Answer 1

The equation of line is: 2x-7

Step-by-step explanation:

Given points are:

(1,-5) = (x1,y1)

(9,11) = (x2,y2)

The slope-intercept form of equation of line is given by:

$y=mx+b$

Calculation of slope:

$m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{11+5}{9-1}\\=\frac{16}{8}\\=2$

Putting the value of slope

$y=2x+b$

Putting (9,11) in the equation

$11=2(9)+b\\11=18+b\\b=11-18\\b=-7$

Putting the values of b and m

$y=2x-7$

The equation of line is: 2x-7
