For number 7 the slope is 3/5 with a y intercept of -1. For number 8 you make a line going up and down from 5. Slope is 0 and there is no y intercept.
Answer:
B
Step-by-step explanation:
We know that a1 = -1, and an = 2 * an-1.
We already know that the first time, a1, is -1. We're given the formula to find the next terms in the sequence.
For a given term in this sequence, it will be 2 times the last item in the sequence.
an = 2 * an-1
a2 = 2 * a2-1 = 2 * a1 = 2 * -1 = -2
a3 = 2 * a3-1 = 2 * a2 = 2 * -2 = -4
a4 = 2 * a4-1 = 2 * a3 = 2 * -4 = -8
a5 = 2 * a5-1 = 2 * a4 = 2 * -8 = -16
a6 = 2 * a6-1 = 2 * a5 = 2 * -16 = -32
Answer: y=10/3x-14
Step-by-step explanation:
convert y-7=10/3(x+1) into y=mx+b (lope intercept form)
y=10/3x+8
if m= 10/3 and it's <em>parallel</em> that means the <em>slope stays the same </em>
plug in point (-6,6) for (x,y) into y=mx+b to find b (y-intercept)
6=10/3(-6)+b
6= -19.99 +b
b= -13.99= -14
so y=10/3x-14
