The slope of the line is 1, and the y intercept is -1. What is the equation of the line written in slope intercept form?
2 answers:
Answer:
Step-by-step explanation:
The equation of a line in slope-intercept form is given by :-
(1)
, where m = slope pf line.
c= y-intercept.
Given : Slope of line = 1
Y-intercept = -2
So , put m= 1 and c= -1 in equation (1) , we get
[∵ (+)(-)=(-)]
Hence, the equation of the line written in slope intercept form :

Answer:
Hence, Grasshopper will land on the ground after 1.5 sec.
Step-by-step explanation:
It s given that:
The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:
Now we are asked to find:
In how many seconds will the grasshopper land on the ground?
i.e. we have to find the value of t such that h(t)=0
i.e.
i.e. we need to find the roots of the given quadratic equation.
On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:
As time can't be negative hence we will consider:
Hence, grasshopper will land on the ground after 1.5 sec.
