The formula is y=mx+b
To get the slope or m, use this formula
(the second y minus the first y)/(the second x minus the first x)
Now set it up.
(10-7)/(2--1)
3/3=slope is 1.
y=1x+b
Insert one of the points for x and y.
i will do (-1,7)
7=1(-1)+b
7=-1+b
8=b
Insert this into the final equation:
y=1x+8
Try it out. If you're not sure, try both points. If it works, then you set it up correctly.
Answer:
26V + 2
Step-by-step explanation:
This is the same as saying f(g(x)), where x = 26
First, lets figure out what g(x) is equal to when x = 26
g(26) = V(26) - 1 = 26V - 1
Now we input 26V - 1 into f(x) for x
f(26V-1) = (26V-1) + 3 = 26V + 2
Answer:
-5/4 or -1.25
Step-by-step explanation:
the points are (-6, -3) and (-2, -8)
the formula for slope is y2-y1/x2-x1
y2 is -8
y1 is -3
x2 is -2
x1 is -6
(-8+3)/(-2+6)
(-5)/(4)
-5/4 or -1.25
Answer: -2 73/100
Explanation: keep the -2 and just look at the .73. The .73 is in the hundredths place so you put it over 100.
