Answer:


y=-(7)/(1)x+2

Explanation:

The slope of -7=


-(7)/(1)

so fractional slope is


y=mx+b

Substituting slope into a fraction,


y=-(7)/(1) x+b

Point is 0,2 so substitute in x and y.


2=-(7)/(1) (0)+b

Solve the equation.


b=2

So the equation for the line is


y=-(7)/(1)x+2

Hope this helps :D

Y = -7x + b
2 = 0 + b, b = 2
Y = -7x + 2
