The slope -intercept form of linear equation is y=mx+b.
Where m= slope and b=y-intercept.
Formula to find m is,
The line passes through (-1, 8) and (3, 16) . So, we can plug in x1=-1, y1=8, x2=3 and y2=16 in the above formula. So,
So, m=2
Now we can plug in m=2, x=3 and y=16 in y=mx+b to get the value of b. So,
16=2*3+b
16=6+b
16-6=b
So, b=10.
Answer:
17 hours
Step-by-step explanation:
Because 10+7 is 17 so that is your answer
Answer:
B)
Step-by-step explanation:
Answer:
- W'(2, 14)
- X'(1, 4)
- Y'(4, 11)
Step-by-step explanation:
To translate 2 left, subtract 2 from every x-value.
To translate 6 up, add 6 to every y-value.
__
W' = W +(-2, 6) = (4-2, 8+6)
W' = (2, 14)
__
X' = X +(-2, 6) = (3-2, -2+6)
X' = (1, 4)
__
Y' = Y +(-2, 6) = (6-2, 5+6)
Y' = (4, 11)
