perpendicular to the line that has an x-intercept of 2 and a y–intercept of -4.
Negative reciprocal of (1/2) is that described slope.
Meaning, .
Continuing with point slope form,
Do what you need to do.....

slope-intercept form: where is a slope and is y-intercept
given:
the graph of f passes through (,)
and
is perpendicular to the line that has an x-intercept of and a y–intercept of
if (,) on a line, then we have
........eq.1
if line is perpendicular to the line that has an x-intercept of and a y–intercept of , then our line has a slope negative reciprocal to the slope of the line that has an x-intercept of and a y–intercept of
first find the equation of the line that has an x-intercept of and a y–intercept of
if the line that has an x-intercept of , then the point (,) is on a line
so, we have
........... eq.2
if the line that has an y-intercept of , then the point (,) is on a line
so, we have
.......substitute in eq.2 and find
........... eq.2
so, the equation of the line is perpendicular to the line that has an x-intercept of and a y–intercept of is
since the slope is , our line will have the slope which is is the negative reciprocal of the
so far we have and we need to find
use ........eq.1, substitute
so, the equation of a line we are looking for is:
