Question 284134: How do I write an equation when the slope is -3 and the y-intercept is 5?
Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
y = mx + b is the basic slope-intercept form of a linear equation, where
m = slope
b = y-intercept (recall, the y-intercept is the point where x=0)
.
slope = -3 = m
.
y-intercept = 5 = b,
or
(0,5)
.
y = -3x + 5
.
A good check is what is the x-intercept, and then graph it.
.
The x-intercept is where y=0.
.
0 = -3x + 5
.
x=5/3
.
or (5/3,0)
.
Graphing can be used to check
.
