Answer:

y = -7x - 2

Explanation:

To write this into an equation, we need to use the y = mx + b formula.

y = mx + b

-30 = -7(4) + b <--- Substitute 4 as x, and -30 as y.

-30 = -28 + b

+ 28 +28 <--- Add 28 on both sides of the equation.

-2 = b

Final equation:

y = -7x - 2

Answer:

  • equation: y = -7x - 2

Step-by-step explanation:

using the formula: y - y1 = m ( x - x1 )

: y - -30 = -7 ( x - 4 )

: y + 30 = -7x + 28

: y = -7x + 28 - 30

: y = -7x - 2
