Write the equation in slope-intercept form. what are the slope and y-intercept?
-9x+10y=-9
a. y=9/10x+9/10; slope: 9/10; y-intercept: 9/10
b. y=9/10x-9/10; slope: 9/10; y-intercept: 9/10
c. y=-9/10x+9/10; slope: 9/10; y-intercept: 9/10
d. y=9/10x-9/10; slope: 9/10; y-intercept: -9/10

-9x + 10y = -9. move the x value to the other side.

10y = -9 + 9x. divide all values by 10

y = -9/10 + 9/10x. make your answer in slope intercept form. (y=mx+b)

y= 9/10x - 9/10

slope : 9/10

y int: -9/10

Your answer Would be Letter 'D'.

d

step-by-step explanation:

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
