You would insert your coordinates to see if it is a solution.
x=5 y=6.5 So your new equation is
6.5 = -1/2(5)+9
This is a solution because -1/2(5) is equal to -2.5, and then -2.5 + 9 is equal to 6.5
Answer:
The slope is -3/4
Step-by-step explanation:
6x + 8y = 12
Write the equation in slope intercept form y = mx+b where m is the slope
Subtract 6x from each side
6x-6x + 8y = -6x+12
8y = -6x+12
Divide each side by 8
8y/8 = -6x/8 +12/8
y = -3/4x +3/2
The slope is -3/4
The equation x² - 8x = 16 will equal to (x - 4)² = 32 so option (C) will be correct.
<h3> What is an expression?</h3>
An expression is a mathematical proof of the equality of two mathematical expressions.
Expressions are collections of variables, numbers, addition, subtraction, multiplication, and division.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given,
x² - 8x = 16
x² - 8x - 16 = 0
Add and subtract 16 to the left-hand side
(x² - 8x +16) - 16 - 16 = 0
(x - 4)² - 32 = 0
(x - 4)² = 32
Hence the expression (x - 4)² = 32 will equal to x² - 8x = 16 .
