Question

Re-write the following equation in slope-intercept form: 5x + 10y = 30

a) y = -0.5x + 3
b) y = -2x + 6
c) y = -0.2x + 3
d) y = -1x + 3

Answer 1

To rewrite the equation 5x + 10y = 30 in slope-intercept form, subtract 5x from both sides and divide by 10. The correct answer is a) y = -0.5x + 3.

Step-by-step explanation:

To rewrite the equation 5x + 10y = 30 in slope-intercept form, we need to isolate the y-variable on one side of the equation. First, we can subtract 5x from both sides to get 10y = -5x + 30. Then, we can divide both sides of the equation by 10 to get y = -0.5x + 3. Therefore, the correct answer is a) y = -0.5x + 3.
