Find the equation of the line whose x-intercept is 8 and y-intercept is -2. write the equation in slope-intercept form.
goldfiish [28.3K]
Find the slope, m = (change in y) / (change in x)

                     0-(-2)
Here, m = ------------- = 1/4
                     8 - 0
y-k = m(x-h) becomes         y+2 = (1/4)(x), or y = (1/4)x - 2

Then the desired equation is   y = (1/4)x - 2 (slope-intercept form)

33 points!! The line contains the point (4,-2) and is perpendicular to 4x+3y=-6 The equation of the line is:
Deffense [45]

Answer:

y = 3/4 x - 5

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals. We find the slope of the given line. Then we can find the slope of the reciprocal.

4x + 3y = -6

Solve for y.

3y = -4x - 6

y = -4/3 x - 2

The slope of the original line is -4/3.

The slope of the perpendicular is 3/4.

Now we need to find the equation of line with slope 3/4 that contains point (4, -2).

y = mx + b

-2 = (3/4)(4) + b

-2 = 3 + b

-5 = b

b = -5

The equation is

y = 3/4 x - 5
