Question

A line has a slope of 9/4 and a y-intercept of -14. Which equations represent the line? 
Choose ALL answers that are correct.

B. 9x + 4y = 56
C. y = 9/4x - 14 
D. y = 9/4x + 14

texaschic101 · Answer

y = 9/4x - 14 <=== this one

y = 9/4x - 14 --- multiply entire equation by common denominator of 4
4y = 9x - 56 --- subtract 9x from both sides
-9x + 4y = -56 <=== this one

9x - 4y = 56 <== this would also be one, but it is not an answer choice

so, A and C
