Q
Q: Determine the point of intersection of the lines y = 2x + 1 and y = -x + 4.
Solution:
Setting 2x + 1 = -x + 4 gives 3x = 3, hence x = 1. Substituting back gives y = 3.
Steps: 9
Show Steps
Step 1: Write down the two equations: y = 2x + 1 and y = -x + 4.
Step 2: Since both equations equal y, set them equal to each other: 2x + 1 = -x + 4.
Step 3: To solve for x, first add x to both sides: 2x + x + 1 = 4.
Step 4: This simplifies to 3x + 1 = 4.
Step 5: Next, subtract 1 from both sides: 3x = 3.
Step 6: Now, divide both sides by 3 to find x: x = 1.
Step 7: Substitute x = 1 back into one of the original equations to find y. Using y = 2x + 1: y = 2(1) + 1.
Step 8: This simplifies to y = 2 + 1, so y = 3.
Step 9: The point of intersection is (1, 3).
