I have to find the slope-intercept form of the line with the given properties. x-intercept = 4, y-intercept = 9

Question

this precalc is hard

Answer 1

x-intercept = (4,0)

y-intercept = (0,9)

 

y = mx+b

 

where:

• m = the slope
• b = the y-intercept = 9 (given in the problem statement)

 

Use the slope formula to find the slope given the two points (4,0) and (0,9):

 

      m = (y₂-y₁)/(x₂-x₁)     

      m = (9-0)/(0-4) = -9/4

 

      y = -(9/4)x + 9
