To find the slope and y-intercept of the equation x + 2y = 8, we need to rewrite it in slope-intercept form, which is in the form y = mx + b, where m represents the slope and b represents the y-intercept.
First, let's rearrange the equation to solve for y:
x + 2y = 8
Subtract x from both sides:
2y = -x + 8
Divide both sides by 2:
y = -1/2x + 4
Comparing this equation to slope-intercept form, we can observe that the slope (m) is -1/2 and the y-intercept (b) is 4.
