Answer:
D. 
Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

It is 0...77% sure i guess.
Answer:
Cost of medium iced caramel latte = $3.59
Step-by-step explanation:
Assume;
Cost of medium iced caramel latte = x
Cost of blueberry muffin = y
So,
On Thursday
x + y = 5.18......eq1
On Friday
2x + 3y = 11.95.....eq2
Eq1 × 3
3x + 3y = 15.54......eq3
eq3 - eq2
x = 3.59
Cost of medium iced caramel latte = $3.59
- The coordinates of a point satisfies the equation of a line if the point lies on the line
- If a single point satisfies the equations of two lines, the point is on both lines, so the lines will intersect at that point.
- This means that each point where the two lines touch is a solution to the system of equations
- This means that if you substitute the x and y values of the point for x and y in the equations, both equations will be true

Explanation:</h2>
You haven't given any option. However, I have tried to complete this question according to what we know about system of linear equations. Suppose you have the following system of two linear equations in two variables:

The fist equation is the blue one and the second equation is the red one. Both have been plotted in the first figure below. As you can see, (-3, -3) is the point of intersection and lies on both lines. So this point is a solution of the system of equation and we can also say that it touches both lines. On the other hand, if you substitute the x and y values of the point for x and y in the equations, both equations will be true, that is:

Also, you can have a system with infinitely many solutions as the following:

Here, every point that is solution of the first equation is solution of the second one. That is because both equations are basically the same. If we divide eq (2) by 2, then we get eq (1).
