Write the equation of the line that is parallel to y=2x+9. and goes through the point (3,1)

First we find the slope of the given line as both the lines are parallel therefore their slopes are equal.

To find slope of given line we compare the equation with point slope form i.e.

On comparing

We get

As the required line is parallel to given line its slope is equal to given line

Required line pass through

Using point slope form

Here

Putting the values and solving

is the required equation

Hope this will help

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

step-by-step explanation:

2*5=10

4*15=60

60+10=
