Answer:
y = -4/5x +1
Explanation:
Slope formula says that y=mx+b.
In terms of words, it means that y is equivalent to slope times x plus the y-intercept.
Slope= rise/run. You rise 4 and run 5. (which is 4/5) However, the slope is negative so be careful with that.
We know the y intercept is 1 so replace that for b.
Put it together and you get y=-4/5x+1
hope this helps!!
