Question

Need help with slope? Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3, -4).

Answer 1

Point slope form is y-y=m(x-x)
You fill in each second variable with the coordinate, and m represents slope.
x is 3, y is -4, and slope is -3, in this scenario.
y+4 = -3(x-3)

Answer 2

Ok, i was confused because it has been awhile since i have done slope.

Answer 3

\(\bf \begin{array}{lllll}
&x_1&y_1\\
&({\color{red}{ 3}}\quad ,&{\color{blue}{ -4}})\quad
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= -3
\\ \quad \\

y-{\color{blue}{ y_1}}={\color{green}{ m}}(x-{\color{red}{ x_1}})\qquad \textit{plug in the values and solve for "y"}\\
\qquad \uparrow\\
\textit{point-slope form}\)

Answer 4

well.... no need to solve for "y" in this case... since you need in point-slope form anyhow
