Answer: The value of a is -6.
Step-by-step explanation:
To do this we need to find the y-intercept first.
-2= 4(1/2) + b
-2=2+ b
-2 -2
b= -4 so now the y-intercept is -4 so we will now have the equation y= 1/2x -4
so now put -4 into the equation for x and solve for y.
y= 1/2(-4) -4
y = -6

Answer:
This is true!
Step-by-step explanation:
It is natural because it is a positive integer greater than 0, it's whole because its not negative and it is an integer.
Answer:
44
Step-by-step explanation:
I believe I already explained how to solve this type of equation in the last question I helped you with. So I am just going to explain how to do it the faster way.
Use the equation:
To find the base, add 5.5 and 2.5 together. The sum is 8. Then multiply this times the height, which is 5.5. So 8 x 5.5 = 44
