Answer: A
Step-by-step explanation: put it into point slope-form
y-ysub1=m(x-xsub1)
m=slope=(-2-3)/(2-(-1))=-5/3
ysub1 is 3 and xsub1 is -1
so substitute: y-3=-5/3(x-(-1))
y-3=-5/2(x+1)
1 kilo=1000 meters
so
216 kilo=216 000 meters
the missing number should be the square root of the last number times 2 for a perfect trinomial
so square root of 49 = 7
7*2 =14
so the missing number should be 14
All of our equations are in slope-intercept form. Slope-intercept form is y=mx+b. m stands for the slope, and b stands for the y-intercept. Our y-intercept is 3. Therefore, we can eliminate the equations that say the y-intercept isn’t b. Next, we can find the slope. We have the points (0, 3) and (3, 2). The formula for slope is y2-y1/x2-x1. 2-3 is -1, 3-0 is 3. Our slope is -1/3. After eliminating those without the y-intercept, we have A or D. We know that the slope is -1/3, so the answer must be D.
I find that turning the fractions into decimals helps in this situation.
9/16 = 0.5625
8/15 = 0.5333
so 9/16 is greater then 8/15
