Answer:
Point coordinates: (5,5)
Explanation:
Q = (1,4)
4 units to the right is the same as <em>x + 4</em>
1 unit up is the same as <em>y + 1</em>
The translation's coordinates are (1+4,4+1)
Answer:
Step-by-step explanation:
<u>Equation of a Line</u>
Two variables x and y are linearly dependent when they are related by the equation
where m is the slope and b is the y-intercept, or the value of y when x equals 0. We are given a particular equation for the line such as b=0, so we only need one point to compute m. That point is (-1,-2):
It follows that
Thus the equation of the line is
