Find the equation of the line that goes through points (1,6) and (3,10)

Question

A) y= -2x+4

B) y= 4x+2

C) y= 2x+4

D) y= 7x+13

E) None of the above

Answer 1

equation of line is y = mx + b, where m is slope

Find the slope between the two points:

(10-6)/(3-1) = 2

substitute one of the points the line goes through into equation of line with slope m = 2

y = mx + b

6 = 2 * 1 + b

4 = b

equation of line

y = 2x + 4
