Answer:it’s (2,5)
Step-by-step explanation:
Answer: 32
Step-by-step explanation: Hope it helps
The incorrect step in Talia's solution is the step 4 which is "step 4 is incorrect because it shows and incorrect substitution of slope value into the point-slope form". The correct steps are as follow:
step 1: choose a point on the line which is (2,5)
step 2: choose another point on the line which is (1,3)
Step 3: determine the slope which is m = rise / run. The line runs 1 unit and rises 2 units so the slope is m = 2/1
step 4: substitute point on the line (2,5) and the slope of the line such as:
y-y1 = m (x-x1)
y-5 = 2 (x-2)
This is the correct steps.
{ 1,-3,9...}
an = a1 * r^(n-1)
a1 = first term = 1
r = common ratio = -3
so ur formula is : an = 1 * -3^(n-1)
