Find the slope of the line that contains the points (-1,9) and (-3,4). then write the equation of the line in slope-intercept form

The slope will be
  (9-4)/(-1-(-3)) = 5/2

In point-slope form the equation can be written as
  y = (5/2)(x+1)+9
This can be simplified to slope-intercept form
  y = (5/2)x + (11 1/2)

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
