2+2 equals 4 and 2x2 also equals 4
D Mean is 7 and median is 7
Mean refers to the average of the a given set of data. This is obtained by adding all the data and dividing it to the number of data sets. The mode is the most frequently occurring digit in a data set while the median is the middle number when you arrange the data from lowest to highest or vice versa.
Answer:
y = 7x +2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (- 1, - 5 )
m = = = 7
the line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = 7x + 2 ← equation of line
