Answer:
gradient = -1
Step-by-step explanation:
identify the y intercept ( the point where it meet the y- axis ) which denoted by c in the formula y =mx + c
in the graph :the y- intercept is 5 (c)
take the coordinate of any point that passes through the line :- for example (2,3)
in (2,3), the value of x is 2
the value of y is 3
using the formula y = mx + c find m with is the gradient ( unknown )
y = mx + c
3 = m2 + 5
2m + 5 = 3
we sent + 5 to the right and it changes sign to become -5
2m = 3 -5
we substract -5 from 3
2×m = -2
we send 2 to the other side so that m can be alone, it change to become divide since it was multiply
m = -2 ÷ 2
m = -1
the gradient ( unknown ) = -1
Answer:
it's 5
Step-by-step explanation:
the initial value is the y-intercept
in a y=mx+b equation b is always the y-int. or initial value

Answer:
It will take 2.6 s for the ball to hit the ground.
Step-by-step explanation:
This is a standard physics problem
The equation that defines the movement of Ryans baseball is given by the initial velocity, and the acceleration
Distance = Do + Vo*t + 0.5*a*t^2
Where
Do is the initial distance.
(Do = 2m over the ground)
Vo is the initial velocity = 12m/s
a is the acceleration that is exerted on the body (in this case a = g = -9.8 m/s^2 )
t is the time
We substitute in the equation, and solve for t (time)
(0)= 2+ (12)*t + 0.5*(-9.8)*t^2
We get that
t = 2.606 s = 2.6 s
