Are you supposed to assume that the function y is linear or that it is quadratic?
576-400
If linear, find the slope: m = ------------- = 176
6-5
Then the equation you want is y-400 = 176(x-5), or
y = 176x - 880 + 400, or y = 176 - 480.
Answer: - Just a minus sign
Subtracting a positive is subtraction.
<h3>The
- changes the second (+) to a negativ </h3>
Step-by-step explanation:
Perhaps tthe point of this question would br to contrast it with
(+)-(-) becomes +
<h3>That would be
Subtracting a negative changes to addition.</h3>
Important: If you're discussing squares, please express "the square of x" as x^2 (not as x2).
Please note that your y=x^2+3 is NOT a line. I will assume (probably incorrectly!) that you meant y=2x+3. The slope of this line is 2, so the slope of any line perpendicular to y=2x+3 is -1/2.
Now use the point-slope equation of a straight line:
y-8 = (-1/2)(x-1) (answer)
