Write an equation in slope for a line that passes through (3,4) (and has a y intercept of -8)

Vlad [161]

Answer:

Part 1) The equation in slope intercept form is $y=4x-8$

Step-by-step explanation:

Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)

we know that

The equation of a line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$b=-8$

$point\ (3,4)$

substitute

$4=m(3)-8$

solve for m

$4+8=3m$

$3m=12$

$m=4$

therefore

$y=4x-8$

<h3>Answer: Choice C. (-x, -y)</h3>

Explanation:

Focus on one point, such as A = (1,2). Note how it moves to point A ' = (-1, -2). Both x and y coordinates have been flipped from positive to negative. The rule therefore is $(x,y) \to (-x,-y)$ . This describes a 180 degree rotation (either clockwise or counterclockwise, it doesn't matter). Points B and C follow the same idea.
