Answer:
there are several ways to write, and find slope...see explanation
Step-by-step explanation:
Way 1: slope Intercept- y=mx+b
step 1: find where the line crosses the Y axis(the one running up and down...thats is your "b" so if the line crosses at -2...it would be this: y=mx-2
Step 2:from the point where the line crosses the Y axis, count how many up/down and Left/right to the next point..so if you go up 2 right 1, it would look like this y=2x-2
Up=positive
down=negative
left=negative
right=positive
Answer:
Step-by-step explanation:
So the equation used to find the axis of symmetry in a quadratic function is
x = -b / 2a
So our b term is = 3
and our a term is = 2
So:
-3 / 2(2)
or
x = -3 / 4
Answer:
y = 1.4x + 21.4
Step-by-step explanation:
Given :
Total cost and number of units made have a linear relationship
Mathematically,
Total cost, y = b * number of units made, x + c
If cost increases by $1.4 for each additional unit, the slope, b = 1.4
If total cost of 24 units = $55
Total cost = 1.4 * number of units made + c
55 = 1.4*24 + c
55 = 33.6 + c
c = 55 - 33.6
c = 21.4
c = intercept
The linear relationship between total cost and number of units made is :
y = 1.4x + 21.4
Answer:
True
Step-by-step explanation:
because is it asking that the hight (y) is in what place in a more spicific wording
85.5 as a fraction is 85 2/10 which is simplified to 85 1/5
