2 Answers
Explanation:
From the question, we know that the line has
a gradient of
and that it passes through the point
we know that all straight lines take on the form
From the given information we know that
Now we need to find
So let's sub the information that we know in.
Now we have our constant, so lets finish of the equation by implementing it in.
Explanation:
#"the equation of a line in "color(blue)"slope-intercept form"# is.
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#"here "m=5#
#rArry=5x+blarrcolor(blue)"is the partial equation"#
#"to find b substitute "(1,-4)" into the partial equation"#
#-4=5+brArrb=-4-5=-9#
#rArry=5x-9larrcolor(red)"in slope-intercept form"#
