A:
Both problems are similar, so we can work the general case first.
For ax +by = c, you can solve for y to put the equation into slope-intercept form. by = -ax +c . . . . . . subtract the x-term y = (-a/b)x +c/b . .. divide by the coefficient of x
The slope is the x-coefficient, -a/b; the y-intercept is c/b. The function is an odd-degree polynomial function, so its domain and range are both "all real numbers."
2x+3y=18 Slope-intercept form: y = (-2/3)x +6 Domain: all real numbers Range: all real numbers Slope: -2/3 Y-intercept: 6
3x-4y > 16 Slope-intercept form: y < (3/4)x -4 Domain: all real numbers Range: all real numbers Slope: 3/4 Y-intercept: -4
_____ You will note that the inequality symbol in y < (3/4)x -4 is reversed from that in 3x -4y > 16. That is because in solving for y, we divided by -4. When you multiply or divide an inequality by a negative number, you must reverse the sense of the inequality.
