How do you find the slope given y=2x+9?

3 Answers

slope #=2#

Explanation:

Given equation

#y=2x+9#

Comparing the above equation with the standard form of slope-intercept form #y=mx+c# we get

Slope: #m=2#

y-intercept: #c=9#

#"slope "=2#

Explanation:

#"the equation of a line in "color(blue)"slope-intercept form"# is.

#•color(white)(x)y=mx+b#

#"where m is the slope and b the y-intercept"#

#y=2x+9" is in this form"#

#"with slope "=2" and y-intercept "=9#

See below:

Explanation:

The key realization is that our equation is of the form

#y=mx+b#, commonly called slope-intercept form, where #m# is the slope and #b# is the #y#-intercept.

We see that our coefficient on #x# is #2#- this is our slope.

We also see that our constant is #9#- this is our #y#-intercept.

Hope this helps!
