Find the equation of the line with y-intercept -2 and passing though the point (2,5). show your work. what is the equation of a line perpendicular to this line, but with the same y-intercept? (have no idea how to do this can someone explain)

equation of a line with y intercept of neg.2 is y=mx-2

you could use pint slope[y-y1=m(x-x1)], but i preffer slope intercept form [y=mx+b]

5=m2-2

move 2 to the other side

7=m2

divide both sides by 2

3.5=m

so, the slope is 3.5

equation for a line that passes through point (2,5) with a y intercept of -2 is y=3.5x-2

the equation of a perpendicular line to the line y=3.5x-2 has a slope that is negative reciprical of 3.5

we keep the everything on y=3.5x-2 same except the slope.

negative reciprical slope of 3.5 is -

simplify

so, the equation of a line perpendicular to the first one is y=-2/7x-2

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
