Answer: " y = x + 4 ".

Explanation:

We shall write the equation of a line written in slope-intercept format;
that is, " y = mx + b " ;

in which y is isolated as a single variable on the 'left-hand' side of the question, and with no "coefficient"—
{except for the implied coefficient of 1 }; and:
m refers to the slope of the line—and is the coeffcient of x ;
and b refers to the y-intercept—or more specifically, the value of the y-coordinate when "x = 0" [i.e. the value of the y-coordinate where the line crosses the x-axis].
So: We can plug the given values: m = 1 ; and b = 4 ; into the equation:
" y = mx + b " ; as follows:

→ y = 1x + 4 ; Note: By convention, we often omit the 1 as the coefficient of x —since the 'stand-alone' variable, x ; has an implied coefficent of x ; and we can write the equation:
y = x + 4 ; which is our answer.|
