Slope of a line passing though point (x1,y1) nd (x2,y2) is
(y2-y1)/(x2-x1)
we have
(1,-3) and (3,-5)
x1=1
y1=-3
x2=3
y2=-5
slope=(-5-(-3))/(3-1)=(-5+3)/(2)=-2/2=-1
slope=-1
Answer:
A: 43.55
Step-by-step explanation:
Place value can be defined as the numerical value representing a digit owing to its position in a number. Some examples of the various place values used in representing each digit are tenths, hundredths, thousandths, unit, tens, hundreds, thousands etc.
For example, in the number 43.55;
- The place value of 4 is tens.
- The place value of 3 is units.
- The place value of 5 is tenths.
- The place value of 5 is hundredths.
Rounding up to the nearest tenth simply means to have 1 significant figure after the decimal point.
Therefore, 43.55 to the nearest tenth is 43.6
