Is my answer to this true or false question correct? (y = mx + c question)?

The question was:





True or false?


y = 10 - 2x is the equation of the line with gradient 10 that cuts the y-axis at (0, -2).





My answer was: False, it is the equation of the line with gradient -2 that cuts the y-axis at (0, 10)

Yes, your answer is correct. Gradient (slope) is the number next to x, whereas the other number (which does not multiply x) is the y-coordinate of the point of intersection between the line and the y-axis.Is my answer to this true or false question correct? (y = mx + c question)?
Yes, you are correct.
