Answer:
1
Step-by-step explanation:
both are parrelel lines
Answer:
(0,1) and (-2,9)
Step-by-step explanation:
A point (x,y) lies on the graph of f(x) =
if it satisfies the condition y = 
<h3>
(0,1):</h3>
x = 0 and y = 1.
This point satisfies the required condition as
= 1
Hence, this point <u>is</u> on the graph of f(x) = 
<h3>
(3,27):</h3>
x = 3 and y = 27.
This point doesn't satisfy the required condition as
=
≠ 27
Hence, this point i<u>s not</u> on the graph of f(x) = 
<h3>
(-2,9):</h3>
x = -2 and y = 9.
This point satisfies the required condition as
=
= 9
Hence, this point <u>is</u> on the graph of f(x) = 
<h3>
(-1,
):</h3>
x = -1 and y =
.
This point satisfies the required condition as
y =
=
= 3 ≠ 
Hence, this point <u>is not</u> on the graph of f(x) = 
Answer:
-2/0
Step-by-step explanation:
I am pretty sure this is called undefined.
If you have a graphing calculator, you can simply type it into y= and it will graph it for you. But if you need coordinates, the line runs through (0,2) , (4,5) , and (-4,1)
Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.
