<u>ANSWER: </u>
If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1
<u>SOLUTION:</u>
Given, two points on line l have coordinates (0, A) and (2, −3),
And the slope of the line is A,
We need to find a value.
We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by

Here,in our problem,

now, substitute the values in formula we get

2A = -3 –A
2A+ A = -3
3A = -3
A = -1
Hence, the value of A is -1.
Y=5x
Explanation:
You would take two points and use the slope formula
Y2-y1/x2-x1
So I took the points (0,0) and (1,5)
5-0/1-0
5/1
5= the slope
So now we know y=5x+b and since it shows us on the graph where the line crosses the y axis we know the y intercept will be zero because it crosses at 0. When the y-intercept is 0 we don’t even need to list it.
$400.72 - This is how it’s done.
Answer:
6 adults
Step-by-step explanation:
Let
x -----> the number of children
y ----> the number of adults
we know that
The ratio

so
using proportion
Find the value of y for x=(20-12)=8

therefore
6 adults
Answer:
-1, 0 and 1
Step-by-step explanation:
Let's work through this step by step.
x goes from -2 to 2 so we will check each integer in between.
f(-2) and g(-2) is the first one. The table shows f(-2)=-8 and g(-2)=-2, so f(-2) does not equal g(-2)
Now we just keep doing this for x=-1,0,1, and 2
f(-1) = -1 and g(-1) = -1 so f(-1)=g(-1)
f(0)=0 and g(0)=0 so f(0)=g(0)
f(1)=1 and g(1)=1 so f(1)=g(1)
f(2)=8 and g(2)=2 so f(2) does not equal g(2)
So there were three xs that made f(x) = g(x). -1, 0 and 1, so those are your answers.
