Answer:
y = x + 7
Explanation:
Your original equation was:
y - 3 = (x+4)
First distribute
= (x+4)
Since there is no a value, then there is an invisible one and your result is:
y - 3 = x + 4
Then add 3 to both sides to get:
y = x +4 +3
y = x + 7
Since the slope-intercept form of a line is y = mx + b
where m is the slope and b is the intercept, then your equation is now in slope-intercept form.
