Equation of a line that goes through (1,4) and (2,2)

Well, the slope of this line would be -2.

So, You need to find what the Y intercept is. (I'm sorry but I do not know what that is)

Once you have the Y intercept, your equation would look like this:

Y= -2x + (or -) your y intercept.

If you have a y intercept that is negative, it would be minus and if your y intercept is positive, it would be plus.

The original equation without numbers is y=mx+b

M= the slope

B= the y intercept

I really hope this helped you :)

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
