What is the value of (y) at (x=0) in the line (y=-x+6)?
Answer and explanation
Correct answer: 6
Substituting x=0 in the equation gives y=-(0)+6=6. Therefore, the correct value is 6. It is also the y-intercept because the line meets the y-axis where x=0. The value -1 is the coefficient of x (the slope), not the value of y. Exam tip: To find the y-intercept, always put x=0.
