A line's y-intercept is 4, and its slope is 1/2. What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.

Asystem of equation is shown below 6x - 2y equals 3 . and 5x + 3y equals 4. would you solve by substitution or elimination? and why
