Answer:
Rob saved $30 while he earned $75.
Step-by-step explanation:
Given:
For every 15 dollars he earns babysitting, he saves 6 dollars.
For money earned = $15
Money saved = $6
We will first find the percentage amount saved by rob
Percentage of amount is calculated by dividing money saved with for money saved and then multiplied by 100.
Percentage amount saved =
Now we need to find the amount of money save when money earned $75.
Amount of money saved can be calculate by multiplying money earned with percentile amount saved.
Framing in equation form we get;
Amount saved =
Hence Rob saved $30 while he earned $75.

Hi there!
Recall that slope-intercept form is:
y = mx + b
Where m = slope
In this instance, we are given a slope of 4,
therefore:
y = 4x + b
Substitute in the x and y coordinates of the point given:
0 = 4(3) + b
0 = 12 + b
Substract 12 from both side:
-12 = b
Therefore, the equation would be:
y = 4x - 12
Graph the equation by finding x and y values or using a calculator:
x = 0, y = 4(0) - 12 = 12 (0, 12)
x = 1, y = 4(1) - 12 = - 8 (1, -8)
x = 2, y = 4(2) - 12 = - 4 (2, -4)
x = 3, y = 4(3) - 12 = 0 (3, 0)
And so forth:
