Question

What is the equation of the line which includes points (2, 6) and (0, 0)?


y = -3x + 1

y = -3x

y = 3x

y = 3x + 1

Answer 1

Is it c?

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 2}}\quad ,&{\color{blue}{ 6}})\quad &({\color{red}{ 0}}\quad ,&{\color{blue}{ 0}})
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}
\\ \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 3

is it not 3x?

Answer 4

what did you get for the slope?

Answer 5

3

Answer 6

oh h.. yeap..is 3x

Answer 7

c is correct?

Answer 8

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 2}}\quad ,&{\color{blue}{ 6}})\quad &({\color{red}{ 0}}\quad ,&{\color{blue}{ 0}})
\end{array}
\\\quad \\

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

y-{\color{blue}{ 0}}={\color{green}{ 3}}(x-{\color{red}{ 0}})\implies y=3x\)

Answer 9

so yeap
