OR..
you can use your Tl-30XIIS calculator and do.. "21 A b/c ( the button) 28"
y = - x + 8
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = -x + b Input Slope
Step 3:
7 = - 1 ( 1 ) + b Input x and y
Step 4:
7 = - 1 + b Multiply
Step 5:
b = 8 Add 1 on both sides
Hope This Helps :)
Just substitute 0 instead of f (x),therefore
The answer option is C
