The equation of the line that is parallel to
and passes through the point (8,3) is
, which corresponds to option E.
Explicação
## Step 1The given equation of the line is
. We need to convert this equation into the slope-intercept form, which is
, where
is the slope of the line and
is the y-intercept.## Step 2To convert the given equation into slope-intercept form, we divide the entire equation by 20. This gives us
.## Step 3The slope of the given line is
. Since parallel lines have the same slope, the slope of the line we are looking for is also
.## Step 4We are given a point (8,3) that lies on the line we are looking for. We can use the point-slope form of a line equation, which is \(y - y_1 = m(x - x_1)\), where \((x_1, y_1)\) is a point on the line and
is the slope.## Step 5Substituting the given point and slope into the point-slope form gives us \(y - 3 = -\frac{1}{4}(x - 8)\).## Step 6Solving this equation for
gives us the equation of the line in slope-intercept form:
.
