Let's solve each question step by step.
### Question 1:
To find the x-intercept of the equation \(-4x + 5y = -20\), we set \(y = 0\).
\[-4x + 5(0) = -20\]
\[-4x = -20\]
\[x = 5\]
**Answer**: x = 5
---
### Question 2:
To find the y-intercept of the equation \(-4x + 5y = -20\), we set \(x = 0\).
\[-4(0) + 5y = -20\]
\[5y = -20\]
\[y = -4\]
**Answer**: y = -4
---
### Question 3:
To find the x-intercept of the equation \(9x - 5y = -45\), we set \(y = 0\).
\[9x - 5(0) = -45\]
\[9x = -45\]
\[x = -5\]
**Answer**: x = -5
---
### Question 4:
To find the y-intercept of the equation \(9x - 5y = -45\), we set \(x = 0\).
\[9(0) - 5y = -45\]
\[-5y = -45\]
\[y = 9\]
**Answer**: y = 9
---
### Question 5:
To rewrite the equation \(8x + 4y = 28\) in slope-intercept form (y = mx + b), we solve for \(y\).
1. Subtract \(8x\) from both sides:
\[4y = -8x + 28\]
2. Divide everything by \(4\):
\[y = -2x + 7\]
**Answer**: y = -2x + 7
---
### Summary of Answers:
1. x = 5
2. y = -4
