4b.) Write an equation using point-slope form with a slope of 2.3 and goes
Yuri [45]

Answer:

y+3.2=2.3(x-4.5)

Step-by-step 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)
