Answer:

#y = color(red)(1)x + color(blue)(4)#

Or

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

Explanation:

We can use the slope intercept formula to find the equation.

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.

Substituting the values from the problem results in:

#y = color(red)(1)x + color(blue)(4)#
