Answer:
A change from 64 to 80 represents a positive change (increase) of 25%
Step-by-step explanation:
Hello!
This is real simple!
So let's look at your first ordered pair, (-2,0)
-2 is the x-coordinate, 0 is the y-coordinate. 0 is the origin - or the center - of your graph. Don't put a point yet!
Next, -2 is to the left, so look for -2 on your graph (or count two to the left) Now put a point there. You have plotted (-2,0) on your graph!
Let's try another.
(0,4)
Look at 0 on your graph. The 4 is the y-coordinate, indicating that you'll go up on the y-axis.
Go up 4 on your y-axis
Put a point, you plotted (0,4)
One more?
(2,0)
x. y
Go to positive 2 on your x-axis (since it is the x-coordinate). Notice the y-coordinate is 0, you don't need to go up! Plot your point
You plotted (2,0)
I hope I helped. Please ask if you still need help.
Answer:
a) 3x + y = 5
Step-by-step explanation:
Insert the coordinates into the Point-Slope Formula FIRST, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>with their CORRECT signs. Remember, in the Point-Slope Formula, all the negative symbols give the OPPOSITE term of what they really are. So, with that being stated, here is how you will set it up: <em>y + 1 = -3(x - 2).</em> After this [Distributive Property], convert to Slope-Intercept Form by moving "-1" to the right side of the equivalence symbol, resulting in <em>y</em><em> </em><em>=</em><em> </em><em>-</em><em>3x</em><em> </em><em>+</em><em> </em><em>5</em><em>.</em><em> </em>Go to your answer choices and see if this is there. No. So then, we try going from Slope-Intercept to Standard by moving "3x" to the left side of the equivalence symbol to end up with <em>3x + y = </em><em>5.</em><em> </em>This answer choice is found, there you are finished.
I think first option is that right answer
