65/100 or 13/20
Both work, it's just that 13/20 is simplified
Add the x's and divide by 2 and then add the Y's and divide by 2
X: (-8 + -7)/2 = -15/2
Y: (-7+-8) /2 = -15/2
midpoint = (-15/2, -15/2)
Answer is C
Answer:
Shipping charge was $11.51
Step-by-step explanation:
(1.075)($349.50) = $375.71 (cost of desk, with tax, without shipping)
Subtracting this amount from the total paid, $387.22, we get $11.51 as the shipping charge.
Check: Does $349.50 + $11.51 + $24.47 = $387.22? Yes
here x intercept is -1, so coordinate would be (-1,0)
we use two points (2,7.5) and (-1,0) to find the slope
slope=-7.5/-3 = 2.5
now let us use slope m =2.5 and point (-1,0) to get the y intercept
y=mx+b
0=2.5(-1)+b
b=2.5
plugging value of m and b in slope intercept form to get the equation
y=2.5x+2.5
