Answer:
Find the value of b using the formula for the equation of a line.
y = mx+b
Replace the known value of m in the slope y-intercept form of the equation.
y=(1)x+b
Replace the known value of b in the slope y-intercept form of the equation.
y=(1)x+4
Simplify the slope y-intercept form of the equation.
Remove parentheses.
y=(1)x+4
Multiply 1 by x
y=1x+4
Remove parentheses.
y=(1)x+4
Multiply x by 1
this is the answer : y=x+4
i hope this helps.
