A line in a graph passes through the point (2,0) and has a slope of -1/2.

1.) What is the y-intercept of the line plotted?

2.) What is the equation of the line that passes through (2,0) with a slope of -1/2?​

Answer:

1) y-intercept = 1

2) Equation of line = [tex]y=-\frac{1}{2}x+1[/tex]

Step-by-step explanation:

Slope-intercept form:

The equation of line is represented by [tex]y=mx+c[/tex].

Here, m represents the slope of line and c represents the y-intercept.

(1).

The objective is to determine the y-intercept of the line.

From the given information:

(x,y) = (2,0) and  [tex]m = -\frac{1}{2}[/tex]

Substitute the given above values in [tex]y=mx+c[/tex] to solve for c.

[tex]0=-\frac{1}{2}\times (2)+c[/tex]

[tex]0=-1+c[/tex]

[tex]1=c[/tex]

Hence, the y-intercept of the line is, 1.

(2).

The objective is to determine the equation of line that passes through (2,0) with a slope of -1/2.

Given that:  [tex]m = -\frac{1}{2}[/tex] and c = 1(from above problem (1))

Substitute these above values in [tex]y=mx+c[/tex] we have:

[tex]y=-\frac{1}{2}x+1[/tex]

Hence, equation of line that passes through (2,0) with a slope of -1/2 is, [tex]y=-\frac{1}{2}x+1[/tex]
