Okay, so this is exponential. The formula for the exponental function is Y=ab^x
a is the y-intercept
b is the rate/ratio
x is the time
According to the graph, (remember the y-intercept is in the y-axis) so 2 is the y-intercept.
Knowing what the y-intercept is, you know what the answer is.
A.
P-6=19; p=13
so you just plug the value of P into the problems P and solve the equation
(13) - 6 = 19
7=19
so...that's incorrect because 7 can't equal 19 making the problem No solution. if that's wrong then idk what they're teaching in math any more...
0x + y = 1 is the standard form of (3, 1) with m = 0
<u>Solution:</u>
We have been given a point and slope of an equation and have been asked to write it in the standard form.
The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.
The given point is (3,1) and the slope is 0
To write in standard form we will first write it in point slope form and then rearrange it into a standard from.
The point slope form of line is given as:

Where "m" is the slope of the line
Here in this problem, 
y - 1 = 0(x - 3)
y - 1 = 0
y = 1
since the above equation doesn’t have an ‘x’ term we convert into a standard form as follows:
0x + y = 1
This is the standard form for the given point and slope of a line.
Answer:
1. y = x + 7
Step-by-step explanation:
Find the slope
Choose two points and find the slope using rise/run
(1,8) (2,9)
9-8/2-1
1/1 = 1 = m (slope)
Find b using the slope and one point
m=1 (1,8)
8 = 1 (1) + b
8 = 1 + b
7 = b
Fill in m and b into y = mx + b
y = 1x + 7
