Answer:

1/8

Step-by-step explanation:

when adding or subtracting fractions, we will always want the denominators to be the same.

We multiply the denominator 4 by 2 so we get an equal denominator of 8.

3/8 - 2/8

and we subtract numerators which will give us:

1/8

Show a graph Slope function of -1 with a y intercept of 3

castortr0y [4]

Answer:

<h2>In the attachment.</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have m = -1 and b = 3. Substitute:

$y=-1x+b\to y=-x+3$

The graph is a straight line. Therefore we need only two points to plotting the graph.

One we have, the y-intercept (0, 3). Calculate other point.

Put any value of x to the equation of a line and calculate the value of y:

For x = 3:

$y=-3+3=0\to(3,\ 0)$
