Answer:

To identify the slopes and y-intercepts of the given lines, we need to rewrite them in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

a) 5x + 9y - 25 = 0

First, isolate y:

9y = -5x + 25

y = (-5/9)x + 25/9

Slope: -5/9

Y-intercept: 25/9

b) 4x + 5y + 5 = 0

Isolate y:

5y = -4x - 5

y = (-4/5)x - 1

Slope: -4/5

Y-intercept: -1

c) 5x + 2y - 4 = 0

Isolate y:

2y = -5x + 4

y = (-5/2)x + 2

Slope: -5/2

Y-intercept: 2

d) 3x - 5y - 5 = 0

Isolate y:

-5y = -3x + 5

y = (3/5)x - 1

Slope: 3/5

Y-intercept: -1
