Question

Which is an equation in point-slope form for the given point and slope?

Point: (1, 9); Slope: 5

Answer 1

A.
y – 1 = 5(x + 9)

B.
y – 9 = 5(x + 1)

C.
y – 9 = 5(x – 1)

D.
y + 9 = 5(x – 1)

Answer 2

whats with the question marks? kind of hard to tell what the problem is.

Answer 3

i'm sorry it's my computer

Answer 4

ok i see it now

Answer 5

its C

Answer 6

if you need help with point slope this is a good site http://www.freemathhelp.com/point-slope.html

Answer 7

\(\bf \begin{array}{lllll}
&x_1&y_1\\
&({\color{red}{ 1}}\quad ,&{\color{blue}{ 9}})\quad
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies 5
\\ \quad \\

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

Answer 8

yup C

Answer 9

thanks i have more

Answer 10

Which is an equation in point-slope form for the given point and slope?

Point: (–3, 7); Slope: 4

Answer 11

A.
y – 7 = 4(x – 3)

B.
y – 7 = 4(x + 3)

C.
y + 7 = 4(x + 3)

D.
y + 7 = 4x – 12

Answer 12

The equation for point-slope form is \[y-y _{1}=m(x-x _{1})\] where m is the slope, y1 is the y-intercept, and x1 is the x-intercept.
If the points are (-3,7) and the slope is 4, the equation in point-slope form is
A. y-7=4(x-3)
