3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3
Answer:
3 hours and 30 minutes
Step-by-step explanation:
Since both of these times are in the P.M., each hour has 60 minutes and 2:30 is half, add 30 minutes to get 3:00 P.M. and then add 3 hours to get 6:00 P.M. . 3 hours and 30 minutes added to 2:30 P.M. equals 6:00 P.M. :)
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept
To find "m", you can use the slope formula and plug in the two points:




The slope is 0 so:
y = mx + b
y = 0x + b [any number multiplied by 0 is 0]
y = b
To find "b", you plug in either of the points into the equation (since both of their y values are 1]
y = b
1 = b
Your equation is:
y = 1 (This is a horizontal line)
I’m not sure what your teacher wants you to do but I would do 110-50=60
