Answer:
y = 5x -2
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (8 -3)/(2 -1) = 5
The y-intercept is given by the formula:
b = y -mx
b = 3 -5(1) = -2
Then the slope-intercept form equation is ...
y = mx +b
y = 5x -2 . . . . . . . . using the m and b we found above
Answer:
a. 10, 16
b. 211, 311
c. 10 , 12.5
d. -13, -22
Step-by-step explanation:
In an arithmetic sequence, there is a constant difference, which is the difference between a term and the previous term. We find the constant different for each sequence, and we add it to the second term to find the third term. Then we add the constant difference to the third term to find the fourth term.
a.
4 - (-2) = 6
3rd term: 4 + 6 = 10
4th term: 10 + 6 = 16
b.
111 - 11 = 100
3rd term: 111 + 100 = 211
4th term: 211 + 100 = 311
c.
7.5 - 5 = 2.5
3rd term: 7.5 + 2.5 = 10
4th term: 10 + 2.5 = 12.5
d.
-4 - 5 = -9
3rd term: -4 + (-9) = -13
4th term: -13 + (-9) = -22
