Answer:
y = -7x
Explanation:
Take two points from table: (-4, 28), (-3, 21)
Find slope:
[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]
[tex]\rightarrow \sf slope\ (m): \dfrac{21-28}{-3-(-4)} = -7[/tex]
Now find equation:
[tex]\sf y - y_1 = m (x - x_1)[/tex]
[tex]\rightarrow \sf y - 21 = -7(x - (-3))[/tex]
[tex]\rightarrow \sf y = -7(x +3) + 21[/tex]
[tex]\rightarrow \sf y = -7x -21 + 21[/tex]
[tex]\rightarrow \sf y = -7x[/tex]
