What is the y-intercept of the line described by the equation below? y=x-3? A. (0, 1) B. (0, -1) C. (0,-3) D. (0,3)
The y intercept is the value of y when x is equal to 0, so just set x=0 and find y! y = 0-3 y=-3 The answer is C: (0,-3) I hope this helped! ^-^
The y-intercept is found when the x-coordinate is equal to zero, so if you plug 0 into the x-variable of the equation, you can find the intercept. y = x - 3 Plug in 0 for x y = 0 - 3 Subtract y = -3 So when x = 0, then y will equal -3. This means that the y intercept of the equation will be C. (0, -3).
