Question

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

Answer 1

In the attachment.

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)`
