What is the slope if the line x+3y = 10

-1/3

Step-by-step explanation:

We want to get the equation in slope intercept form (y=mx+b)  where m is the slope and b is the y intercept

x+3y = 10

Subtract x from each side

x-x+3y = -x+10

3y = -x+10

Divide each side by 3

3y/3 = -1/3x +10/3

y = -1/3x +10/3

The slope is -1/3 and the y intercept is 10/3

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
