Input in standard form the equation of the given line.

the line with m = -1 /2 and b = 1

In y = mx + b form, the slope will be in ur m position and the y intercept will be in the b position.

y = mx + b
slope(m) = -1/2
y int (b) = 1
so ur equation is : y = -1/2x + 1but we need it in standard form

y = -1/2x + 1add 1/2 to both sides
1/2x + y = 1cant have fractions, so multiply everything by 2
x + 2y = 2 <== standard form
