Answer: B not sure if I’m right though .
Step-by-step explanation:
You just multiply each of the coordinates by the scale factor. No extra work since it’s from the origin.
Doing this gives:
J’ (2.5 , 10)
K’ (15 , 10)
L’ (15 , 2.5)
M’ (2.5 , 2.5)
Step-by-step explanation:
y — yı = m(x – xı) equation of a line
Points A(1,3) and B(2,1)
Slope (m) = (y2 – y1) / (x2 – x1)
(1 –3) / (2 – 1)
–2/1
–2
Thus, y –3 = –2 (x – 1)
y – 3 = –2x + 2
y –3 + 3 = –2x + 2 + 3
y = –2x + 5
Let's assume that you are to graph the inequality.
1. Graph -3x + 4y = 12. Note that the x-intercept is (-4,0) and the y-intercept is (0,3). Use a dashed line, not a solid line, due to the ">" sign.
2. Choose a test point (e. g., (0,1) ) and subst. these coordinates into -3x + 4y = 12. Is the equation then true or false? If true, shade the area (on one side of -3x + 4y = 12 or the other) in which the test point (0,1) lies. If false, shade the other side of -3x + 4y = 12.
Hello:
let : x the length and : y the <span>width
</span> xy the <span>area.
x = 3y...(1)
x = 15m
the area is : 15×5 =75 m²
