so for this equation, I would do 7/8 = 72/x
1 72
- = -
8 x
Cross multiply to get 72 * 8 = 1x
solve for X 576 = x
Answer:
i think its 90% but im not 100% sure
Step-by-step explanation:
Hello :
<span>2x+3y=6
3y = - 2x +6
y = (-2/3)x +2
</span>the slope is : (-2/3)
the y- intercept when : x = 0 : y = (-2/3)(0) +2 = 2
<h3>
Answer is -3</h3>
How I got that answer:
The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.
m = (y2 - y1)/(x2 - x1)
m = (2 - (-4))/(-2-0)
m = (2 + 4)/(-2-0)
m = 6/(-2)
m = -3
A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.
goodnight
