Question

Write the equation for the line in slope-intercept form.

  1. y= -1x+3
  2. y= 4x+3
  3. y=1/4x+3
  4. y= -4x+3

Hint:

equation of line in slope intercept form is y = mx + c
where c is intercept on y axis and m is slope of line

The correct answer is: y= 4x+3


    From the graph, slope(m) of the line is 4 and the y-intercept(b) of the line is 3
    Substitute the values of m and b in slope-intercept form.
    We get, y= 4x+3

    Slope of line is = fraction numerator y subscript 2 minus y subscript 1 over denominator x subscript 2 minus x subscript 1 end fraction
