HOW TO:
* use slope intercept form
1) find the slope
slope = rise/run (rise divided by the run)
slope = -4/2
slope = -2
2) find the y-intercept (just the point where the line intersects the y-axis)
y-intercept is (0,-4)
3) use slope-intercept form:
y = mx + b (m stands for the slope, b stands for the y-intercept)
y= -2x + (-4)
y= -2x - 4
So your equation is y= -2x-4
Answer:
A
Step-by-step explanation:
U mean y = 0.9^x ...?
.
its exponential decay...
.
because.. y = (1/e)^x is exponential decay...
.
(1/e) < 1
Hey there!
To find the x-value of the midpoint, you add the two x-values of the endpoints and the divide the result by two.
-12+0=-12
-12/2=-6
So, the x-value of our midpoint is -6.
To find the y-value of a midpoint, you do the same thing as with the x-values but with the y-values.
2+14=16
16/2=8
Our y-value is 8.
Therefore, our midpoint is (-6,8)
I hope that this helps!
It's associative property:
a · (b · c) = (a · b) · c
3 × (2 × 6) = (3 × 2) × 6
