which equation is the point-slope equation of the line that passes through the points (-2,-1) and (7,-4)?
1 answer:
Answer:
B (for question 7)
Step-by-step explanation:
To find the slope, we use the equation 
.
m = (-4+1)/(7+2) = -3/9 = -1/3
Since B is the only option that would give a slope of -1/3, B must be the answer.
(you can use this same method for question 8)

Step-by-step explanation:
(6*2.5)/6.5 = 30/13
Answer:
x = 6, x = -2
Step-by-step explanation:
Given the function;
f(x) = 3|x – 2| + 6
When x = 6
f(x) = 3|x – 2| + 6
= 3|6– 2| + 6
= 3(4) + 6
= 18
When x = -2
f(x) = 3|x – 2| + 6
= 3|-2 – 2| + 6
= 3(4) + 6
= 18
Therefore; <em>both x= 6 and x= -2, will give f(x) = 18</em>

Answer:
y<=-x+3 and y<=2x+1
Step-by-step explanation:
y=-x+3 is the orange line. The shaded region is below so its y<-x+3
y=2x+1 is the blue line. The shaded region is below so y<2x+1
