2) Find the slope of the line. (If an answer is undefined, enter

for the equation in the form

Ax + By = C, the slope is -A/B, so ....

or change it to the form y = mx + b, where the slope is m
4x + 5y = 20
5y = -4x + 20

y = ....

y= -4/5x +5

so the slope is -4/5

correct

thank you Reiny

To find the slope of the line, you need to rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope.

Given equation: 4x + 5y = 20

Step 1: Subtract 4x from both sides to isolate y:
5y = -4x + 20

Step 2: Divide both sides by 5 to solve for y:
y = (-4/5)x + 4

Now that the equation is in slope-intercept form, we can see that the coefficient of x (-4/5) represents the slope of the line.

Therefore, the slope of the line is -4/5.
