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

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

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 :)
The expression above is composed of 3 terms which are: 3x, 2y, and 8z. All of the terms are the product of two items. The first term is a product of 3 and x. The second is a product of 2 and y. Lastly, the third is a product of 8 and z.
<span>Thus, the expression is a sum of three products and there are only three terms. This answer is the second among the four choices.
