<u>Answer:</u>
A) slope of equation 3x+4y-12=0 is m= and y-intercept is 3
B) slope of equation 2x+y=1 is m=-2 and y-intercept is 1.
C) slope of equation 2x-y=0 is m=2 and y-intercept is 0.
<u>Solution:</u>
The slope - intercept form equation of line is given as
y=mx+c --- eqn (1)
Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.
c is the y – intercept which is the value of y at the point where the line crosses the y-axis
a) Given that
3x+4y-12=0 --- eqn (2)
On converting equation (2) in slope intercept form, we get
4y=-3x+12
On comparing equation (3) and (1) we get slope of equation (2) is and y-intercept is 3.
b) Given that
2x+y=1 …(4)
On converting equation (2) in slope intercept form, we get
y=-2x+1 …(5)
On comparing equation (5) and (1) we get slope of equation (4) is m=-2 and y-intercept is 1.
C)Given that
2x-y=0 …(6)
On converting equation (6) in slope intercept form, we get
y=2x …(7)
On comparing equation (7) and (1) we get slope of equation (6) is m=2 and y-intercept is 0.

Step-by-step explanation:
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
I reccomend the search bar up at the top ("What is your question") before you ask questions, to make sure they're not already answered.
There is a formula d = rt, distance = rate*time. So
r = d/t.
r = 7mi/55min = 0.127mi/min
Or another way to see this:
