Question

what is an equation of the line that passes through the point (4 −6) and has a slope of −3

Answer 1

use y=mx+b
your slope is -3
m=-3
y=-3x+b
now we need to figure out the "b" value that is your y intercept

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1\\
&({\color{red}{ 4}}\quad ,&{\color{blue}{ -6}})\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 3

(4,-6) was given to you
this means x=4 and y=-6

Answer 4

y=mx+b
-6=-3(4)+b
finish solving for b

Answer 5

Please solve in writing formation

Answer 6

writing formation what is that?

Answer 7

typed

Answer 8

am I not typing???????? ok sorry don't know what to tell you
the problem is 99% done, just solve for b or use the other formula provided by jdoe0001

Answer 16

hmm looks to me pretty straightforward above

Answer 17

I need some one to solve clearly

Answer 18

\(\bf \begin{array}{lllll}
&{\huge x_1}&{\huge y_1}\\
&({\color{red}{ 4}}\quad ,&{\color{blue}{ -6}})\quad
\end{array}
\\\quad \\

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

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