Answer:
Person above did the standard form wrong.
Step-by-step explanation:
slope = -1/2.
y-intercept = 1.
slope-intercept form : y = 1/2x + 1.
standard form : x + 2y = 2.
In standard form, there can't be any fraction. So, you have to get rid of it by multiplying both sides by the reciprocal of -1/2 which is -2. then that's what you get. Your final answer will have ax as negative which is not allowed so you multiply all sides with -1 and are left with x + 2y =2.
