If the line (y=(k-3)x+8) has slope (5), what is the value of (k)?
Answer and explanation
Correct answer: 8
A line in the form y = mx + c has slope m, the coefficient of x. Here, the coefficient of x is k - 3, so k - 3 = 5. Adding 3 to both sides gives k = 8. Option 2 results from moving 3 to the wrong side. Exam tip: In y = mx + c, identify the complete coefficient of x to find the slope.
