The equation of a linear function that passes through the point (3,-1) and has a slope of -2 can be written in point-slope form as y+1=−2(x−3)
.
Which equation can be used to BEST identify the y-intercept of the linear function?
The equation that can be used to best identify the y-intercept of the linear function is y+1=−2(x−3).
To find the y-intercept, we can set x=0 in the equation and solve for y:
y+1=−2(0−3)
y+1=6
y=5
Therefore, the y-intercept is 5.
