Question

a line intersects the point (-3,-7) and has a slope of -3.What is the slope intercept equation for this line

Answer 1

Answer:

  y = -3x -16

Step-by-step explanation:

For problems like this, I like to start with a variation of the point-slope form of the equation of a line:

  y = m(x -h) +k . . . . . for a line with slope m through point (h, k)

For your given values, this is ...

  y = -3(x +3) -7

  y = -3x -9 -7 . . . . eliminate parentheses; next, combine terms

  y = -3x -16
