You would plug in the slope. Which means to multiply 3(-1)
So, y=3(-1)+7
y=-3+7
y=4
Answer:
B is the correct answer
Step-by-step explanation:
1. Find the slope
(3,8) (6,2)
2. See which answers have -2, this narrows down the answers to B. and C.
3. get the y alone for B and C
B: y - 8 = -2 (x - 3)
Using distributing properties it turns into y - 8 = -2x + 6
Then you add 8 to six to get alone so it turns to be y = -2x + 14
C: Doing the same process for it turns you with y = -2x - 14
4. Plug your points into each equation to see which one is the right answer
C. y = -2x - 14
(3,8)
8 = -2(3) - 14
8 = -6 - 14
8 = -20 X
C is wrong
B: y = -2x + 14
(3,8)
8 = -2(2) + 14
8 = -6 + 14
8 = 8 ✔
(6,2)
2 = -2(6) + 14
2= -12 + 14
2 = 2 ✔
Conclusion: B is the right answer
Answer:
y=2x+1
Step-by-step explanation:
y=mx+c
y-intercept is 1
y=mx+1
gradient= rise/run= 2/1= 2
y=2x+1
13x-8≤-32
add 8 to both sides to get 13x≤-24
divide by 13 to get x ≤ -24/13
Answer:
Step-by-step explanation:
we have
we know that
f(-1) is the value of the function for x=-1
so
substitute the value of x=-1 in the function and solve for B
we have
substitute
