Answer:
-3
Step-by-step explanation:
Because f(x) = y so when y=3 what is input value (x)
When y is 3 x is -3
The gradient formula is (y2-y1)/(x2-x1) aka rise/run, where by (x1,y1) and (x2,y2) are two points on the line.
In this case, the gradient
= -5-(-2))/(2-(-2))
= -3/4
So you add whats in parentheses first which gives you -11 then you end up with -11(-3)
Which will equal 33 Thats your final awnser...
33
Y=-3x+1
1 raises the y intercept and -3 is the slope that we can see from (0,1) to (1,-2)
