The table shows four pairs of values of x and y that satisfy the linear equation y = 3x -5. Find the values for P and S.
Let's find the value for P first. For the point (2,P), P is the y-coordinate when the x-coordinate is 2. To solve this, use x = 2 to find P by:
Therefore P = 1.
Similarly, now let's find S. For the point (4,S), S is the y-coordinate when the x-coordinate is 4. To solve this, use x = 4 to find P by:
Therefore S = 7.
From Step 1 & 2, clearly the answer for this question is A..
