Answer:
- slope: -3/4
- y-intercept: -2 . . . . or point (0, -2)
Step-by-step explanation:
Slope-intercept form is ...
y = mx + b
Comparing your equation to this pattern, you can see that your equation is already in this form, with ...
In this form, the coefficient of x (which is m) is the slope of the line. Thus your slope is -3/4. The added constant (which is b) is the y-intercept, the value of y when x=0. Your y-intercept is -2. Expressed as the coordinates of a point, the y-intercept is (x, y) = (0, -2).
