I need to complete the equation of the line through (3 -1) and (4 7). I am really stumped on this topic, please explain the proc
Nana76 [90]

Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.

\frac{-1-7}{3-4}

Which reduces to 8/1=8.

The slope of your equation is 8.

Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.

Plug the slope in:

y=8x+b.

Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).

-1=8(3)+b

-1=24+b

Subtract 24 from both sides.

-25=b

Now plug this into the equation!

y=8x-25 is your final equation.

I hope this helps :)

Here's a graph of a linear function. Write the equation that describes that function. 8 Express it in slope intercept form. Ente
Stolb23 [73]

Answer:

f(x) = \frac{1}{2}x+4

Step-by-step explanation:

Let the equation of the function is,

f(x) = mx + b

Here, m = slope of the line

b = y-intercept

From the graph attached,

y-intercept 'b' = 4

Slope = \frac{\text{Rise}}{\text{Run}}

          = \frac{4}{8}

          = \frac{1}{2}

Therefore, equation of the function representing the graph will be,

f(x) = \frac{1}{2}x+4

Find the equation of a line that is perpendicular to the line y=(1/3)x+4 and contains the point (-9,0)?
torisob [31]

Answer:

y = -3x - 27

Step-by-step explanation:

0 = -3[-9] + b

-27 = b

y = -3x - 27

* Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>]:

⅓ → -3
