Using the equation of the line
y -yo = m (x-xo)
We substitute xo,yo and the slope
y -5 = -8(x-1) .....> y = -8x +8 +5 = -8x +13
y = -8x +13
Answer:
Yes, in a Cartesian Coordinate system each point is given by two numbers. If the question is "where" the function has a max or min value, that's "x", the first number in pair. If the question is "what" is that max or min function value, thats "y", the second number in the pair
Answer:
D(- 2, 9 )
Step-by-step explanation:
Under a reflection in the y- axis
a pont (x, y ) → (- x, y )
Given D'(2, 9 ) is the image of D, then
D(- 2, 9 ) ← are the original coordinates
Since D(- 2, 9 ) → D'(2, 9 )
Answer:
Heyya !
Here's how to do it:-
First write down what's given:-
y -7.2 = 8
Next, we do like this:-
y = 8+ 7.2
We transferred 7.2 to the other side of the ' = ' sign.
When we do so, the sign of the number changes
Here 7.2 was negative first but when we transferred it to the other side, its sign changed to positive.
So,
y = 8 + 7.2
Now, just add it!
8 + 7.2 equals 15.2
<h2>So, the value of y is 15.2 </h2><h2 /><h3>I hope the explanation was clear.</h3><h3>If you still have doubts, let me know in the comments !</h3>
