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:
Given:
Cost of one pound of apples = $1.98
To find:
The cost of 0.75 pound of apples.
Solution:
We have,
Cost of one pound = $1.98
So, cost of 0.75 pound of apples = 0.75 × cost of one pound of apples
Therefore, the cost of 0.75 pound of apples is $1.485.
