Answer:
slope- 9 y-intercept- -7
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
Using the hypothesis test for one sample mean, There is NO SIGNIFICANT EVIDENCE to support the typist's claim
The test statistic :
T = (x - μ) ÷ (s/√(n))
T = (43 - 45) ÷ (15/√70)
T = - 2 ÷ 1.7928429
T = -1.1155
At α = 0.05
Pvalue :
Degree of freedom, df = 70 - 1 = 69
Pvalue = 0.134
Decison region :
Reject if Pvalue < α
Since Pvalue > α We fail to reject the Null

Point slope is in the form y - y1 = m(x - x1)
substitute the values to get
y - 2 = m(x - -8), then simplify
y - 2 = m(x +8)
Answer:
2x²+14x+20
Step-by-step explanation:
Answer:
4y + 28
Step-by-step explanation:
I simply distributed the 4:
1. 4(y+7)
2. 4 times y = 4y
3. 4 times 7 = +28
4. 4y + 28
