Answer:
y = -2x + 4
Step-by-step explanation:
Answer:
17+75=?
Step-by-step explanation:
Answer:
part a= -1
part b= -4
Step-by-step explanation:
f(x) is y. plug in -4 for y and check x
1.
Use the two points given in the graph, and plug them into the slope formula.
slope = m = (y2, y1)/(x2 - x1)
slope = m = (3 - 1)/(0 - 1) = 2/(-1) = -2
Another way of calculating the slope is
slope = m = rise/run
slope = m = -2/1 = -2
As you can see, both methods give you the same answer.
2.
Here you have again two given points, so use the formula.
slope = m = (-3 - 1)/(-2 - 1) = -4/(-3) = 4/3
I think you would have to divide by 2 1/2
43 3/4
_______
2 1/2
Answer: 17 1/2
To check: 17 1/2 × 2 1/2 =43 1/2
