Answer:
Step-by-step explanation:
In order to find the slope of this equation, we can convert it into slope-intercept form, where we can find the slope more easily.
Slope intercept form is usually in the form 
, where m is the slope and b is the y-intercept.
Let's algebraically manipulate this problem so we solve for y.
<em>(Subtract 7x from both sides)</em>
<em>(Divide both sides by -2)</em> 
<em>(Rearrange the equation</em>)
From here, we can now see our equation is , in the form . Since m is the slope, and 
is m, our slope is .
Hope this helped!
Answer:16y I think
Step-by-step explanation:
Take out the y, 2+5-3 is 4, and to the second power is multiplying 4 twice, so 16. theyre all have the same variable to the right, so 16y
Differentiation is part of calculus
differentiation basically allows you to find the gradient of tangent
D is correct because you could put in a value for x and get a true value for y
exg
x=3
y=14(3)-9
y=42-9
y=33
