Question

How to write the equation of the line with m = 3 going through the point (–2, –5) in Slope–Intercept Form.

Answers

  1. Answer: y = 3x + 1
    Step-by-step explanation:
    First of all, Slope Intercept form is this equation;
    y = mx + b
    y = the y-coordinate
    m = slope of the line ( Remember that this type of equation is ALWAYS linear)
    x = the x-coordinate
    b = is the y-intercept
    We can substitute the given values into the equation to find the y-intercept, b.
    ==> y = mx + b
    ==> -5 = 3(-2) + b (simplify)
    ==> -5 = -6 + b (add 6 to both sides to isolate the variable)
    ==> 1 = b
    Since we have the b, the y-intercept , we can write the standard slope-intercept equation;
    y = 3x + 1
    Hope this helped! Have a good day 😉

  2. Answer:
    y = 3x + 1
    Step-by-step explanation:
    the equation of a line in slope- intercept form is
    y = mx + c ( m is the slope and c the y- intercept )
    given m = 3 , then
    y = 3x + c ← is the partial equation
    to find c substitute (- 2, – 5 ) into the partial equation
    – 5 = 3(- 2) + c = – 6 + c ( add 6 to both sides )
    1 = c
    y = 3x + 1 ← equation of line
