The equation 4x − 5y = 40 is in standard form and tells us the x-intercept and y-intercept easily. What are the x and y intercepts for this equation?

• The line crosses the x-axis at (4, 0) and the y-axis at (0, -5)

• The line crosses the x-axis at (4, 40) and the y-axis at (-8, 40)

• The line crosses the x-axis at (0, 10) and the y-axis at (-8, 0)

• The line crosses the x-axis at (-8, 0) and the y-axis at (0, 10)

• The line crosses the x-axis at (10, 0) and the y-axis at (0, -8)

Michele has $50. She plans to save $15 per week until she has a total of $230. Which equation matches this scenario?

• y − 110 = 15 (x − 4)

• y = 50x + 15

• 15x + 50y = 230

• y = −15x + 50
