Question

Write an equation of the line that passes through the point (3,0) and
has the slope, m = -2

Answer 1

y-y1=m(x-x1)
y-0=-2(x-3)
y= -2x+6
2x+y=6 is the required equation of the line.

Answer 2

can you explain how you did that? @dpasingh

Answer 3

y = mx + b
m = -2. So y = -2x + b
The line passes through (3,0). That is x = 3, y = 0. Plug these two numbers in
y = -2x + b and solve for b.
0 = (-2)(3) + b.
b = 6
So y = -2x + 6

Answer 4

Okay we will do the problem step by step so that you can understand it. Since I am using my iPad I can't use the equation format to make it look easier and in practical way.

So there is this formulae conspiring of y=mx+b
I will give you the main aspect or the keywords necessary that usually professors look for.
m=slope
b=y-intercept

Let's now get started
We will now substitute the numbers to the variables.
0=(-2)(3)+b
Now solve for b.
This is easy because -2*3=6. So now that use know, b=6.
