7, 13, 19 and 25 have a common difference: 6.
6 added to 7 gives us 13; 6 added to 13 gives us 19, and so on.
Explicit formula: a(n) = 7 + 6(n-1), where 7 is the first term and n is the counter (1, 2, 3, ...).
The first term is 7 (given). This corresponds to n=1.
The second term is a(2) = 7 + 6(2-1), or 7 + 6, or 13. This corresponds to n = 2.
and so on.
A:B = 2:3
A=126
B=?
126/2=63
63x3=189
A=126
B=189
A:B = 126:189
Slope intercept form is y=mx+b
y= m or 2 because that is your slope but now all you need to is find your begin or find the point (3,7) on the graph.
Answer:
y = mx + b
Step-by-step explanation:
Use that form to find the slope.
The answer would be 180 degrees
