Answer:
y = -(1/7)x+2
Step-by-step explanation:
A slope-intercept form is y = mx + b, where m is the slope and b the y-intercept (the value of y when x=0).
We're given the slope: m = -(1/7):
y = -(1/7)x + b
We can use the given point, (0,2) in this equation and solve for b:
y = -(1/7)x + b
2 = -(1/7)*(0) + b
b = 2
The equation becomes y = -(1/7)x + 0
y = -(1/7)x+2
