A line passes through the point (1, 5) and has a slope of -9.​
vladimir1956 [14]

Answer:

y= -9x+14

Step-by-step explanation:

the equation of a straight line is y=mx+c


m is the slope

And we are given a y and x term

So we substitute these into the equation:


5= -9(1) + c


rearragne to find c


14= c


so the full equation is:


y= -9x+14
