The equation of this tangent line can be written in the form y=mx+b where m is:_________

and where b is:______?

The first to blanks are -43, but what is b? thanks

now for the line

y= mx+b

where x,y is a point on the curve

x=-5, so y= 4x^2-3x+5 solve for the y.

Now that you have x,y, put it in the equation y=mx+b and solve for b.
