[tex]\rule{300}{1}\\\dashrightarrow\large\blue\textsf{\textbf{\underline{Given question:-}}}[/tex]
Find the equation of a line that passes through (2,4) and has a gradient of 3.
[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]
First, let's take a look at our provided information.
| Provided information:-
- Point (2,4)
- Gradient 3
What we need to find:-
- the line's equation
How to find it using our provided information (gradient & point)?
- write the equation of the line in point-slope form
point-slope form:-
- [tex]\sf{y-y_1=m(x-x_1)}[/tex]
how to solve:-
- Replace y₁ with 4
- Replace m with 3 (m is the gradient)
- Replace x₁ with 2
therefore,
- [tex]\sf{y-4=3(x-2)}[/tex]
[tex]\bigstar[/tex] On simplification,
- [tex]\sf{y-4=3x-6}[/tex]
[tex]\bigstar[/tex] On further simplification,
- [tex]\sf{y=3x-6+4}[/tex]
Which results in:-
- [tex]\sf{y=3x-2}[/tex]
Good luck with your studies.
