The answer is y=-6x+3
To find it remember the slope intercept formula is y=mx+b
m= slope and b= y intercept
- It tells you -6 is the slope so you know m= -6 so you have
y=-6x+b
to find the y intercept , use the formula
y-y1=m(x-x1)
You have the points (0,3)
0 is x1 and 3 is y1
plug in x1 and y1 into y-y1=m(x-x1)
you will have y-3= -6(x-0)
M is slope so -6 is the slope
Solve the equation y-3=-6(x-0) and you are left with y= -6x+3
