The value of y so that the line passing through (-1, 9) and (2, y) has a slope of -2 is 3.
<h3>What is the slope of a line?</h3>
The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, the slope can be determined using a variety of approaches.
, where and are two points on the line.
Two points (-1, 9) and (2, y) are given, and a slope of -2.
Put the points in the slope formula to get the value of y.
So, the value of y is obtained as 3.

Answer:
-37
Step-by-step explanation:
1) to find the equation of the given line (its slop-interception form is y=mx+i, where m - slop, i - interception):
a) y=2x+i, where m=2;
b) it is possible to calculate the value of 'i' after the substitution the point (5;-3) into the equation y=2x+i:
-3=2*5+i; ⇒ i= -13;
c) the equation of the given line is y=2x-13.
2) to calculate the value of 'R':
if to substitute the point (-12;R) into the equation y=2x-13, then
R=2*(-12)-13; ⇒ R= -37.
Answer:
x+y<4
Step-by-step explanation:
let the numbers be x and y
x+y<4
x-y>1
The key idea here is that we can't have half a pack (the store owner would be really angry if you cut the packs!). therefore we are really finding the least common multiple of 14 and 5. to find lcm is really hard to explain with the limited technology on this website. i highly recommend you search up ladder method online. i can, however, tell you that the lcm of 14 and 5 is 70 so 70 is the minimum NUMBER of markers (not packs) that blaaine would have to buy.

sorry happy Halloween btw :D
