Question

help me plz
1. write the equation of the line given the slope and y-intercept type your answer in the box in slope-intercept form without skipping any space m=5, y-intercept (0,-3)
2. what is the value of f(2) for the function f(x)=5x+3?(type only the value of your final answer no variables)
3.what is the value of f(g(4) for the functions f(x)=2x+1 and g(x)=2x-5 (type only the value of your final answer no variables

Answer 1

1. y+3=5(x-0)
    y+3-(3)=5x-(3)
     y=5x-3 <------------------answer to problem one.
2. f(x)=5x+3
     f(2)=5(2)+3
      f(2)=10+3
       f(2)=13 <------------------answer to problem two
3A. f(x)=2x+1
        f(4)=2(4)+1
         f(4)=8+1
          f(4)=9 <-------answer for first part of problem three

3B. g(x)=2x-5
       g(4)=2(4)-5
        g(4)=8-5
         g(4)=3 <-------------answer for the second part of problem three.
