Answer:
-1
Step-by-step explanation:
y = -x + 6 the number in front of x is the point slope
so, the answer is -1 because the number in front of x is -1
Answer:
f(4) = 5
Step-by-step explanation:
functions are represented by f(x), so x should be the value in parenthesis and the y value should be what it equals
So the equation we are working with is y=mx +b. If you use the distance formula, you will find the slope. The slope is 1/2 and the y intercept is 0. your equation is y=1/2x. So plug in the point that it gives you.
-2 is your y value.
so it will look like this: (x could also be n)
-2=1/2x...solve....n=-4
We are simplifying this so they are easier to add in your head.
87+33 is easier math to do in your head
so our new estimated number would be 120
