Answer:

y = -3x + 18

Step-by-step explanation:

Write the problem as a mathematical expression.

m = -3, (7, -3)

Find the value of  b  using the formula for the equation of a line.

y = mx + b

b = 18

Now that the values of  m  (slope) and  b  (y-intercept) are known, substitute them into  y =  m x  +  b  to find the equation of the line.

y = -3x + 18

hope this helps :)
