Answer:
y=4x-6
Step-by-step explanation:
to find the slope it's ((y1-y2)/(x1-x2) which in this case is (10-(-6))/(4-0) which is 16/4 aka 4
the y intercept is already given at point (0,-6)
so to write the equation is y intercept form: its y =4x-6
Stevie has 25marbles
Freddie's has 25x2:50marbles
Danny has 50+5:55marbles
