Answer:
Step-by-step explanation:
<u>Point slope form</u>
y=mx +c, where m is the gradient and c is the y-intercept.
To find the gradient, use the formula below:
Substitute the value of m into the equation
To find c, substitute a coordinate into the equation.
When x= -3, y=7,
Thus, the equation of the line is
What I understand from the following info is that you are traveling 40.4 km/hr and travel for 7.5 hours. 40.4 times 7.5= 303km. Hope i help.
When it gets to zero or the intercept
factor
x=4(t^2-8t+9)
x=(4)(t-9)(t+1)
set to zero
t-9=0
t=9
t+1=0
t=-1, false, time cannot be negative
at t=9 seconds
