Q:

Which linear function represents the line given by the point-slope equation y – 8 = (x – 4)?f(x) = x + 4f(x) = x + 6f(x) = x – 10f(x) = x – 12 answer is b

Accepted Solution

A:
Answer: FIRST OPTIONStep-by-step explanation: The slope intercept form of a linear equation is: [tex]y=mx+b[/tex] Where m is the slope and b is the y-intercept. Therefore, to solve the exercise you must solve for y from the  point-slope equation given in the problem: [tex]y-8=x-4\\y=x-4+8\\y=x+4[/tex] You can rewrite it as following:  [tex]f(x)=x+4[/tex]
