Answer:
Slope: 1; Y-int: (0,2)
Step-by-step explanation:
The slope is rise over run, the equation is y two minus y one divided by x two minus x one.
(3-2) / (1-0) = 1
The y-int. is where the line crosses the y-axis, or the x value is 0.
Hope this helps :)
Answer:
For part a)
130 = 10/2[2a+(10-1)d]
Simplify, u get
2a + 9d = 26.................(1)
Also U5 = a + (5-1)d = 3a
Simplify, u get
a= 2d...................(2)
Substituting for a in equation 1,
2(2d)+9d= 26
Solving for d, we get
d = 2
In part b) substituting for d in equation 2 to get the first term
a = 2(2) = 4
Part c) the no. of terms required can be obtained by solving
28 = 4+(n-1)2
n = 13
I could be wrong but I’m pretty sure that there is no solution, and the statement is false.
