hello
the question presented here deals with equation of a line passing through one point
to know that, we need to know two things
1. slope
2. intercept
y = mx+c
m = slope
c = intercept
but the line passes through point (-6,6)
now to find the new equation,
y = mx + c
y = 9x + c
but it passes through (-6,6)
x= -6, y= 6
now let's plug in the values into the equation to find the intercept c
now that we've found c, we can plug it into our equation of straight line
y = 9x + 60
the equation of the line for it passes through points (-6,6) is y = 9x +60
