(5,0) and (8,4)
it’s the only one when graphed that the line (from left to right) goes up,
Let's start with y = 4x + b (since 4 is the slope);
We need to find what number should be put instead of b;
Then, let's see what needs to be done;
Plug in the y and x values from the coordinate (22,12) into y=4x+b;
12 = 4(22) + b
Solve;
12 = 88 + b
12 - 88 = b
b = -76
Remember the equation y = 4x + b? Put the -76 instead of b:
y = 4x + -76
or: y = 4x - 76
That is the equation.
To make it standard form, put x and y both in the left side, with x first then y:
-4x + y = -76
^^Answer!
To answer the question above, substitute the values of the variables x, y and z given to the equation.
2x² - 2(z^4)y² - x²(z^4)
2(-4)² -2(2^2)(3²) - (-4)²(2^4) = -296
Thus, the numerical answer to the question above is -296.
No it’s a relation because the x values repeat (2,2)
