Answer:
Step-by-step explanation:
The equation for a linear function found from two given points is: y = mx + b, where m = slope and b = y-intercept. You can find slope from slope formula:
Given points (5, -4) and (-3, 2):
Using the value m = and the point (5, -4) for x and y:
y = mx + b
-4 = 5(-3/4) + b
-4 = -15/4 + b
-4 = -3.75 + b
-1/4 = b
We have to use pythagorean theorem. The equation is 
so we plug in the numbers (hypothenuse is always C in the equation) 
now we solve:
