Question

4b.) Write an equation using point-slope form with a slope of 2.3 and goes

through the point: (4.5, -3.2)​

Answer 1

`y+3.2=2.3(x-4.5)`

Explanation:

So the point-slope formula looks like this:
`y-y_1=m(x-x_1)`

`y_1` = any y point on the line

`x_1` = any x point on the line

`m` = the slope

And hey, look, we're already given all that information!

So we can just plug those values into the equation:

`y+3.2=2.3(x-4.5)`

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
