Answer:

y = \dfrac{1}{2}x-4

Step-by-step explanation:

<h2>Equation of line in slope y-intercept form:</h2>

       \sf slope = m =\dfrac{1}{2}\\\\Point (2, -3) ; x_1 = 2 \ \& y_1 = -3\\\\\boxed{\bf y - y_1 =m(x -x_1)}

         \sf y - [-3] = \dfrac{1}{2}(x - 2)\\\\y + 3 =  \dfrac{1}{2}x - 2*\dfrac{1}{2}\\\\y + 3 = \dfrac{1}{2}x-1\\\\

                \sf y = \dfrac{1}{2}x - 1 - 3\\\\ y =\dfrac{1}{2}x-4

Scores are 78,81,83, and 76 what must she earn on the fifth test to earn an average test score of 81
iogann1982 [59]
The average value of a data set is equal to the sum of each entry divided by the number of entries. In this case, we have 5 scores, so we can find set up the following equation where x is the fifth score:

\dfrac{78+81+83+76+x}{5} = 81

Now solve for x:

78 + 81 + 83 + 76 + x = 81(5)

318 + x = 405

x = 87

The fifth score must be 87.
