Answer:
Slope = 2
Y-Intercept = 4
Equation of Line is y=2x+4
Step-by-step explanation:
y-intercept is the point in the y-axis, where the line cuts it. So, looking at the graph, the y-intercept would be y = 4
To figure out the slope, we take any two points and calculate using the formula:

Where, m is the slope
is the first coordinate, and
is the second coordinate
<em>Let's take two points as: (-2,0) & (-1,2)</em>
<em />
Plugging these into the formula we get the slope as:

Hence slope is 2
Equation of the line is given as y = mx + b, where m is the slope (in our case 2) and b is the y-intercept (in our case 4). Thus:
Equation of Line: 
You would take the number of ice cream cups which is 12 and divide it by the cost which is 9.60
12/9.60=1.25
Y=mx+b
m=slope
b=yint
y=16500-1500x
y=-1500x+16500
slope is -1500
yintercept is 16500
The square root of 121 is 11 because 11 times 11 is 121.
The answer to this is 7 because you are just taking the value of 7 which is 7
