I assume #3 is 19 because the slope of the line is still the same.
Hope this is right and it helps! I'm not very sure though.
I think 55 because you would multiply 11×5
In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot.
If x-intercept is -2 the line would be vertical as the y-intercept = 0.
-7x-5v^4+5+7x^4+5+9x-=
2x^4+2x+10
