If the original price is 16, then 3/4 of 16 is 12.
$12
Dividing 16 by 4 (the denominator), you get 4. Then 4 x 3 (the numerator) is 12.
y = (1/2)x + 5/2
Step-by-step explanation:
y - 3 = (1/2)(x - 1) is in point-slope form. To obtain the slope-intercept equivalent, solve this equation for y:
y = 3 + (1/2)x - 1/2, or
y = (1/2)x + 3 - 1/2, or
y = (1/2)x + 5/2
