Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- \frac{3}{2}, 0) and (x₂, y₂ ) = (0, \frac{3}{4} )

m = \frac{\frac{3}{4}-0 }{0+\frac{3}{2} } = \frac{\frac{3}{4} }{\frac{3}{2} } = \frac{1}{2} and c = \frac{3}{4} , then

y = \frac{1}{2} x + \frac{3}{4} ( multiply through  by 4 to clear the fractions )

4y = 2x + 3 ( subtract 4y from both sides )

0 = 2x - 4y + 3 , that is

2x - 4y + 3 = 0 ← equation of line
