Answer:
a.
b.
Step-by-step explanation:
We have a differential equation
y''-2 y'-35 y=0
Auxillary equation

By factorization method we are finding the solution


Substitute each factor equal to zero
D-7=0 and D+5=0
D=7 and D=-5
Therefore ,
General solution is

Let 
We have to find Wronskian

Substitute values then we get



a.
We are given that y(0)=-7 and y'(0)=23
Substitute the value in general solution the we get

....(equation I)


......(equation II)
Equation I is multiply by 5 then we subtract equation II from equation I
Using elimination method we eliminate
Then we get 
Substitute the value of
in I equation then we get


Hence, the general solution is
b.
<span>2y=3x-7
y = 3/2x - 7/2
y = 1.5x - 3.5 so slope = 1.5
</span><span>line parallel so it has same slope = 1.5
</span>
y +1 = 1.5(x - 0.5)
y + 1 = 1.5x - 0.75
y = 1.5x - 1.75
answer: equation y = 1.5x - 1.75
