A basketball team played six games. In those games, the team won by 8 points, lost by 7 , won by 9 , won by 11 , lost by 3

BigorU [14]

Answer:

4

Step-by-step explanation:

From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6

The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6

= [8 + (-7) + 9 + 11 + (-3) + 6] / 6

= 24 / 6

= 4

write the slope intercept form of the equation of the line with a slope of -2/5 that passes through 15, -9/2

Sever21 [200]

Answer:

The equation of line in slop-intercept form is y = $\dfrac{-2x}{5}$ + $\dfrac{3}{2}$

Step-by-step explanation:

Given as :

The slope of the a line = m = $\dfrac{-2}{5}$

The line is passes through points $x_1 , y_1$ = 15 , $\dfrac{- 9}{2}$

<u>According to question</u>

Equation of line in slope - intercept form

y - $y_1$ = m × ( x - $x_1$ )

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × ( x - 15 )

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × x - ( $\dfrac{-2}{5}$ ) × 15

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × x + 6

Or, y = $\dfrac{-2}{5}$ × x + 6 - $\dfrac{9}{2}$

Or, y = $\dfrac{-2}{5}$ × x + $\dfrac{12-9}{2}$

Or, y = $\dfrac{-2}{5}$ × x + $\dfrac{3}{2}$

So, The equation of line in slop-intercept form y = $\dfrac{-2}{5}$ × x + $\dfrac{3}{2}$

Hence, The equation of line in slop-intercept form is y = $\dfrac{-2x}{5}$ + $\dfrac{3}{2}$ Answer
