## Answers ( )

Answer:y= -4x+7

Step-by-step explanation:The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Let’s find the gradient of the line first.

Using the above formula,

Susbt. m= -4 into the equation:

y= -4x +c

Subst. a coordinate to find c.

When x=3, y= -5,

-5= -4(3) +c

-5= -12 +c

c= 12 -5

c=7

Thus the equation of the line is

y= -4x+7.
