Question:

How do you find the slope of the tangent line to the graph of the function #f(x)=3-2x# at (-1,5)?

Answers

#"slope "=-2#

Explanation:

#"note that"#

#"slope (m) " =f'(x)" at x = a"#

#f(x)=3-2xrArrf'(x)=-2#

#"this means that the slope at any point on the line is - 2"#

#"of course "f(x)=3-2x" is a linear equation with m = -2"#
