What are the x- and y- intercepts for the graph of 3x+y=15
allochka39001 [22]
To make the equation easier to look at change it to this: 
y = 15 - 3x 
To find the x intercept say y = 0. 
0 = 15 - 3x 
Subtract 15 from each side. 
-15 = -3x 
Divide each side by -3. 
5 = x <–––– x-intercept
The y-intercept of the equation is 15.
Hope this helps!

Determine which equation is written in function form:
Mila [183]

<em>Greetings from Brasil... </em>

A 1st degree function can be written in two ways:

F(X) = AX + B

or

Y = AX + B

note that F(X) = Y

So, looking at the alternatives in the question, only Y = 7X/3 - 8 is equivalent to Y = AX + B, where:

A = 7/3

B = - 8

then

\large{\boldsymbol{\mathbf{Y = \frac{7X}{3}-8\Leftrightarrow Y=AX+B}}}   <em>a function of the 1st degree</em>

answer:

<h2>Y = (7/3)X - 8</h2>
