Answer:

Slope: -1/2 Y-Intercept: -9/4

Explanation:

5x - 4y = 3x + 9

Subtract 3x from both sides

2x - 4y = 9

Divide both sides by -4

y = (-1/2)x + (-9/4)

Answer:

Explanation:

To find the slope of the line represented by the equation 5x-4y=3(x+3), we can rearrange the equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

5x - 4y = 3(x + 3)

5x - 4y = 3x + 9

5x - 3x = 4y + 9

2x = 4y + 9

y = (2/4)x - 9/4

So, the slope of the line is 2/4, which can be simplified to 1/2.

To find the y-intercept, we can set x = 0 in the equation:

y = (1/2)(0) - 9/4

y = -9/4

Therefore, the y-intercept is -9/4.

To find the x-intercept, we can set y = 0 in the equation:

0 = (1/2)x - 9/4

9/4 = (1/2)x

x = (9/4) / (1/2)

x = 9/2

Therefore, the x-intercept is 9/2.
