Answer:

So the slope of this function is \frac{1}{2} and the y-intercept is \frac{3}{2}

Step-by-step explanation:

A first order function has the following format:

y = ax + b

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.

We have the following equation:

-x + 2y = 3

We just have to rewrite this equation

2y = x + 3

y = \frac{x+3}{2}

y = \frac{x}{2} + \frac{3}{2}

Which means that

a = \frac{1}{2}, b = \frac{3}{2}

So the slope of this function is \frac{1}{2} and the y-intercept is \frac{3}{2}
