Answer:
3
Step-by-step explanation:
y = 3 - 1/2x
rewrite equation so the slope is in front
y = -1/2x + 3
plug in 0 for x
y = -1/2(0) + 3
solve for y
y = 0 + 3
y = 3
y- intercept = (0,3)
Step-by-step explanation:
Since this equation is in slope-intercept form, we can easily identify what the slope is, and the y-intercept.
Slope intercept form: y = mx + b
m = slope
b = y intercept
Switch the coefficient and 3:
y = -1/2x + 3
-1/2 = Slope
3 = Y-intercept
Note: If we're asked to graph, using this equation will allow us to graph without solving.
