Answer:
The equation of the line is 4y = -x + 19
Step-by-step explanation:
Firstly, we need to get the slope of the line;
Since it is through two points; we have the slope as;
y2-y1/x2-x1 = (5-3)/(-1-7) = 2/-8 = -1/4
Mathematically, we can write the equation of a straight line line as;
y = mx + c
So we have;
y = -1/4x + c
y = -x/4 + c
To complete the equation, we need the value of c.
we can choose any of the points and insert the x and y value
Thus;
3 = -7/4 + c
c = 3 + 7/4
c = 19/4
So our equation becomes;
y = -x/4 + 19/4
Multiply through by 4
4y = -x + 19

Answer:
Step-by-step explanation:
63 - (-4) = 63 + 4 = 67 <== a difference of 67
or think of it this way..
if its at 63, u subtract 63 just to get to 0....but then u have to subtract 4 more to get to -4......making a difference of 67
Answer:
18
Step-by-step explanation:
This is actually pretty easy. Keep this in mind.
There are 34 total students. 16 of them like bananas and the rest like apples. All you really need to do is count up from 16 to 34 to find the answer.
The simple equation for this is: 34-16
Thus, the answer is 18.
