Question

1.

Write the slope-intercept form of the equation for the line.


A. y = $\frac{1}{2}$x - 1

B. y = – 2x – 1

C. y = 2x – 1

D. y = $\frac{1}{2}$x + 1

Answer 1

Answer:  Here is the answers after I graphed it

1: The equation of the line that has a slope of 1 and a y-intercept of -1 is:

y=1x-1.

...............................................................................................................................................

2: The equation of the line that has a slope of 1 and a y-intercept of -3 is:

y=1x-3.

Step-by-step explanation:  I graphed it

1: You want to find the equation for a line that has a slope of 1 and a y-intercept of -1.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with 1, which is the slope you gave, and

replace b with -1, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of 1 and a y-intercept of -1 is:

y=1x-1.

2: You want to find the equation for a line that has a slope of 1 and a y-intercept of -3.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with 1, which is the slope you gave, and

replace b with -3, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of 1 and a y-intercept of -3 is:

y=1x-3.
