Answer:
The equation of the line is
Step-by-step explanation:
Equation of a line:
The equation of line, in point-slope form, is given by:
In which m is the slope and the point is
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Through (9,-7)
This means that
So
Perpendicular to y = 3x + 4
This line has slope 3, so:
Thus
Answer:
$2.50 + $1.20x $20
Step-by-step explanation:
Monica needs to buy a gallon of milk ($2.50), but she also wants to buy yogurt which is $1.20 each. However, her total cost has to be under $20, and she doesn't know how much yogurt she can get. So the number of cups of yogurt is unknown, so it is represented by the variable x. Now, the milk and the unknown number of cups of yogurt must be less than or equal to $20.
