Question

What is the Y intercept and the slope of the equation Y=3-1/2x

Answer 1

3

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)

Answer 2

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.
