What is the equation of the line that has a slope of 4/5 and a y-intercept of -1?

y = 4/5x -1

Step-by-step explanation:

The slope-intercept form of the equation of a line is ...

... y = mx + b . . . . . . for slope m and y-intercept b

You have m = 4/5 and b = -1. The equation of the line is found by putting these values in their places in the form above.

... y = 4/5x -1

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
