When adding fractions you need to get common denominators then you multiply too times bottom and then boom add and there you go
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
x-intercept is 6, coordinates (6,0)
y-intercept -4, coordinates (0,-4)
gradient= y1-y2/x1-x2= 0-(-4)/6-0= 4/6= 2/3 or 0.667 (3.s.f.)
