Answer:
y = -2x+1
Step-by-step explanation:
We can find the slope of the function by using the equation
m =(y2-y1)/(x2-x1)
We will use the points (3,-5) and (4,-7)
= (-7--5)/(4-3)
= (-7+5)/(4-3)
= (-2)/1
-2
We also know the y intercept ( when x=0 y=1) is 1
If we know the slope and the y intercept, we can use the slope intercept form of the equation of a line
y = mx+b where m is the slope and b is the y intercept
y = -2x +1
