Answer:
40
Step-by-step explanation:
Answer:
M = (Y2 - Y1) / (X2 - X1)
Step-by-step explanation:
First, look at a graph of a line and find two points, 1 and 2. You can use any two points on a line. The slope will be the same between any two points on a straight line.
Note the X and Y value for each of the points.
Now we'll designate the X and Y value for points 1 and 2. We'll use subscripts to identify them in the slope formula.
Hope this helps!
To solve this problem you must apply the proccedure shown below:
To m<span>atch each equation with its y-intercept x must be zero, so you have:
x=0 and solve for y, as following:
1) cx+by=a (0,a/b)
y=a/b
2) bx+ay=c (0,c/a)
y=c/a
3) ax+by=c (0,c/b)
y=c/b
4) cx+ay=b (0,b/a)
y=b/a
