Just isolate f.. buy getting it alone on one side or the other
The slope = 4
y-intercept = -3
The equation of a line in slope intercept form is written as y=mx+b
where m is the slope and b is the y-intercept.
replace m and b with the given information:
The equation is: y = 4x-3
Answer:
for a its 9, 3, -6, x<-6
