1. ### Cartesian slope rationality

If a line coincides with at least two vertices on an infinite Cartesian grid, its slope is rational. If a line coincides with only one vertex on an infinite Cartesian grid, its slope is irrational. If a line coincides with no vertices on an infinite Cartesian grid, its slope is either...
2. ### Slopes&coordinates

Guys, I need help to find coordinates of A given these slopes of lines: 1. AB=-2/5 2. AD=5/2 3. BC=5/2 4. DC=-2/5 IF ABCD IS A RECTANGLE Give me A coordinates
3. ### Finding solution of slopes

Hi, I'm trying to find the solution of these three equation. I have on my calculator (I'm a newbie on calculators), my answers are in coordinates. 1). Y = -7.14x + 13.52 ANS (1.91,.15) Y=12.23x-19.99 2). 1.1x-2.9y = 4.7. ANS (20.27,5.27) 15.95y = 6.05x -38.6 3). 0.3x-y = 16.1. ANS (-9,-19)...
4. ### Can You Calculate Angles Based On The Product Of Slopes?

When two lines intersect, four angles adding up to 360 degrees are formed. If the two lines have slopes that multiply to -1 (perpendicular lines), all four angles are 90 degrees. If the lines are not perpendicular, there will be two pairs of vertical angles, so for example there could be two...
5. ### slop

A housing development outside of Little Rock had sold 240 of its homes 1.6 years after its grand opening. After 4 years and 3 months, the number of homes sold rose to 450. If the number of sales continued to grow at the same rate, how many homes will have been sold at the 6-year mark? ANSWER...
