Quizplus · Accepted Answer

To find the slope (m) and y-intercept, the equation needs to be in slope-intercept form (y = mx + b). Solving 9x + 4y = 47 for y gives y = -9/4x + 47/4, making the slope -9/4 and the y-intercept (0, 47/4).

Use the Equation to Identify the Slope and the Y-Intercept m=94;(0,474)m = \frac { 9 } { 4 } ; \left( 0 , \frac { 47 } { 4 } \right)m=49​;(0,447​)
