Answer:

Step-by-step explanation:
First find the slope:

Use the point-slope form of linear equation: 
(where m is the slope and (x₁, y₁) is a point on the line)
with the found slope and one of the points:

The answer is 5
a^2+b^2=c^2
9+16=25
sq root of 25 is 5
Solving the system of equations, we get value of c= 10 and value of d= 7
Step-by-step explanation:
Solving the system of equations:

Let:

Adding eq(1) and eq(2)

So, value of c = 10
Now putting value of c in equation 1 to find value of y

So, value of d =7
Solving the system of equations, we get value of c= 10 and value of d= 7
