(x2,y2) = (4,7)

(x1, y1) = (5,3)

Construct a linear equation for the linear data presented in the table
yaroslaw [1]

Answer:

y = -7x

Explanation:

Take two points from table: (-4, 28), (-3, 21)

Find slope:

\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\rightarrow \sf slope\ (m):   \dfrac{21-28}{-3-(-4)}  = -7

Now find equation:

\sf y - y_1 = m (x - x_1)

\rightarrow \sf y - 21 = -7(x - (-3))

\rightarrow \sf y  = -7(x +3) + 21

\rightarrow \sf y  = -7x -21 + 21

\rightarrow \sf y  = -7x
