Find the slope first
slope=(2-1)/(-1+3)=1/4=.25
now use the slope and either point to write in point slope form
y-1=.25(x-2)
y-1=¼x-½
to rationalize all the denominators multiply by the last common multiple, here we get 4
4y-4=x-2
then put in the correct order
x-4y=-2
Answer:
A
Step-by-step explanation:
B1 represents the slope of the population regression line so A is the answer
Answer: -2 73/100
Explanation: keep the -2 and just look at the .73. The .73 is in the hundredths place so you put it over 100.
Answer:
angles b and c should be 153° each.
Step-by-step explanation:
We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°
Answer:
48.75
Step-by-step explanation:
340/80=16 1/4
16 1/4*3=48.75
