Answer:

See a solution process below:

Explanation:

Although it may not look like it this equation is in slope-intercept form. The slope-intercept form of a linear equation is: #y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept value.

#y = color(red)(4)x + color(blue)(0)#

Therefore:

  • The slope is: #color(red)(m = 4)#

  • The #y#-intercept is: #color(blue)(b = 0)# or #(0, color(blue)(0))#

Which for this problem also happens to be the #x#-intercept.
