Answer:

x = 2 → (2, 0)

Explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept (0, b)

We have the slope m = -3/2 and the y-intercept b = 3.

Substitute:

y = -3/2x + 3

The x-intercept is for y = 0. Substitute:

0 = -3/2x + 3 add 3/2x to both sides

3/2x = 3 multiply both sides by 2

3x = 6 divide both sides by 3

x = 2
