Question

What is the equation of the line that passes through the points (-1, 3) and (1, 11)?

4x - y = 1
4x + y = 1
x - 4y = -13
4x - y = -7

Answer 1

hey u want help???

Answer 2

ill help uuu

Answer 3

pokay listne

Answer 4

there are 2 points

Answer 5

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ -1}}\quad ,&{\color{blue}{ 3}})\quad &({\color{red}{ 1}}\quad ,&{\color{blue}{ 11}})
\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 move "x" and "y" to left side}\\
\qquad \uparrow\\
\textit{point-slope form}\)

Answer 6

baicall 1 line passes thru 2 points

Answer 7

ther is 1 slope and 1 yincetper that passes throug h2 ponts
