Answer:
y= -2x + 11
Step-by-step explanation:
standard form for lines is y=mx+b
m is the slope and b is the y intercept
we already know that m is -2, so we just need to figure out the intercept.
the point given is (7,-3)
points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y
-3 = -2 (7) + b
-3 = -14 + b
11 = b
so the equation is y=-2x+11
The sequence is defined as
an = 3an - 1 + 7
This means that
a2 = 3(a(2 - 1) + 7
a2 = 3a1 + 7
From the information given ,
a1 = - 4
Thus,
a2 = 3 * - 4 + 7 = - 12 + 7
a2 = - 5
a3 = 3(a(3 - 1) + 7
a3 = 3a2 + 7
a3 = 3 * - 5 + 7 = - 15 + 7
a3 = - 8
a4 = 3(a(4 - 1) + 7
a4 = 3a3 + 7
a4 = 3 * - 8 + 7 = - 24 + 7
a4 = - 17
Thus, the first four terms of the sequence are
- 4, - 5, -
I thinkkkkk ur answer is going to be 98
Answer:
as the first answerer i did not take this yet but i can tell you the formula
slope of XY = y2 - y1 / x2 - x1
