Two ships are sailing parallel to each other. The path of one ship is represented by the straight line y=3x+1. The second ship passes by the point (2; 13). a. Find the equation of the line that represents the path of the second ship.

b. Give coordinates of another point that the second ship will pass through. Find the equation of a line that passes through A(3, 5) and with slope m=4

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

it shoild be o

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
