Answer:14.8 
Step-by-step: 
Use the equation a^2+b^2=c^2
Plug in 13 for a and 7 for b
13^2+7^2=c^2 
Multiply the number by themselves 
13•13+7•7=c^2
169+49=c^2
218=c^2
Square root both side 
14.76=c
Round the nearest tenth
14.8

Answer:
-6
Step-by-step explanation:
The equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The y intercept is the value when x = 0
The y value is -6 when the x value is 0
y = -4x+ (-6)
