Function rule: a = 20w + 115
Slope: 20
Initial value: 115
------------------------------------------
We start with $115 in the account. This is the initial value. Each week we add on $20.
So we add $20 for 1 week
We add 2*20 = $40 for 2 weeks
We add 3*20 = $60 for 3 weeks
etc etc
In general, we add 20*w dollars for w weeks onto 115 to get a = 20w+115
The slope is 20 because this is the rate of change, ie how fast the account grows. It grows 20 dollars per week.

Answer:
Step-by-step explanation:
There are a couple of things you need to understand before this makes sense. First of all, if these 2 triangles are congruent to each other, each corresponding side and angle have the exact same measure. Also, pay close attention to the triangle congruency statement. If the first angle mentioned in the first triangle is angle E, and the first angle mentioned in the second triangle is angle K, then E and K have the exact same measure. The same goes for angle f and angle L; likewise for angle G and angle M. The next super-important-you-HAVE-to-know-this-about-triangle thing is the Triangle Angle-Sum Theorem which says that all the angles of a triangle add up to equal 180 degrees.
We are given that angle E is 60 and angle F (an angle in the same triangle as E) is 35. That means that angle G has to be 180 - 60 - 35 which is 85. Angle G is congruent to angle M, so angle M also measures 85. Second choice down.
Learn your triangle stuff...it doesn't go away all through Geometry class!
The three angles of a triangle add up to 180.
Since you know that two angles add up to 80, you know that the third angle is 100.
