Write an equation in point-slope form and slope-intercept form for
each line.
the line passes through (4, 7), slope = 2

Respuesta :

Answer: y=2x-1

Step-by-step explanation:

Equation of a line that passes through (a,b) and have slope m is given by :-

[tex](y-b)=m(x-a)[/tex]   [point slope form]

Given, Point = (4,7)  , m= 2

Equation in point slope form :   [tex](y-7)=2(x-4)[/tex]

To write in slope intercept form (y=mx+c) , we need to simplify it

[tex]y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1[/tex]

Hence,  y=2x-1
