Answer:

x = ±3

Step-by-step explanation:

x^2 = 9

Take the square root of each side

sqrt(x^2) = ±sqrt(9)

Can I get help with this?
blagie [28]

Answer:

y-4=7(x-1)

Step-by-step explanation:

Hi there!

We are given the slope of the line (7) and the point (1,4) and we need to find the equation in point-slope form.

Point-slope form is given as y-y_{1}=m(x-x_{1}) where m is the slope and (x_{1},y_{1}) is a point

We have all of the needed information for the equation, but let's first label the values of everything in order to avoid confusion

m=7

x_{1}=1

y_{1}=4

now substitute into the formula:

<u>y-4=7(x-1)</u>

Hope this helps! :)
