The slope is -5.

Explanation:

To find this answer, we'll be using the point slope formula:

Y2Y1X2X1=m , where m is the slope.

(0,0) (X1,Y1)
(2,10) (X2,Y2)

Now, plug-in the variables:

10020 = m

Subtract.

102 = m

Simplify.

51 = m

The slope is 5.

(y=5x)

y=5x

Explanation:

Slope-intercept form of an equation: y=mx+b, where m is the slope and b is the y-intercept

Let's first find the slope using the points (x1,y1) and (x2,y2): y2y1x2x1

10020

102

5

Our equation is currently y=5x+b

The y-intercept is in the format (0,b). The point (0,0) is the y-intercept in this case.

y=5x+0

y=5x
