The slope-intercept form is:
y = mx + b
where m = slope, and b = y-intercept.
You need a slope of 1, so m = 1.
You need a y-intercept of -1, so b = -1.
Replace m with 1 and b with -1 in the slope intercept form to get
y = 1x + (-1)
which simplifies to
y = x - 1
Answer:
x stays x in both equations so x stands for x
Step-by-step explanation:
y=3x+6
you can put this into a graphing caculator or draw it yourself.
6 is the y value when x equals 0. and the 3 represents the slope so then it is solved for any y value
Answer:
y-4x-6
Step-by-step explanation:
I'm not 100% sure but I think this is correct!
Answer:
684
Step-by-step explanation:
Using proportions (equivalent ratios), we can find the number of students that make up the 57% out of the total number of people:
Cross-multiply: 100x = (57)(1200) or 100x = 68,400
Divide: 100x/100 = 68,400/100
Solve for x: x = 684 students
