Answer:

The second one: r x-axis. R 90(x,y)

Step-by-step explanation:

You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.

What is the equation of the line that passes through the points (-4,1) and (4-1)

Nitella [24]

Answer:

y=-1/4x

Step-by-step explanation:

METHOD 1: The basic slope-intercept equation is <em>y=ax+b</em>. To achieve the slope with two points, this is the equation:

$m = \frac{y2-y1}{x2-x1}$

All you have to do is insert points (-4, 1) and (4, -1) into their corresponding locations.

$m = \frac{(-1)-1}{4-(-4)}$

With this equation, you will be able to find the slope. Then you can simply graph it to connect the two dots.

METHOD 2: Simply connect the two dots with a straight line (use a ruler or something with a straight edge.) Then count how many spaces up/down and left/right. If the line goes from top to bottom from left to right, it is a negative slope (hence, the -1/4.)

Write the equation, in standard form, for the following relation. B = {(x, y ): (2, 3), (4, 4), (6, 5), . . .}

Rashid [163]

(2,3)(4,4)
slope = (4 - 3) / (4 - 2) = 1/2

y = mx + b
slope(m) = 1/2
(2,3)...x = 2 and y = 3
sub and find b, the y int
3 = 1/2(2) + b
3 = 1 + b
3 - 1 = b
2 = b

ur equation is : y = 1/2x + 2...but we need it in standard form

y = 1/2x + 2
-1/2x + y = 2 ...multiply by -2
x - 2y = -4 <== standard form
