Answer:
Choice 1. -3x + 2y = 5.
Step-by-step explanation:
The slope of the line = y2-y1/x2-x1
= (4 - 1) / (1 - (-1))
= 3/2.
To find the equation of the line we use the point-slope form of the equation of a line:
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line. So using m = 3/2 and the point (1, 4):
y - 4 = 3/2(x - 1)
y - 4 = 3/2 x - 3/2
Multiply through by 2:
2y - 8 = 3x - 3
-3x + 2y = -3 + 8
-3x + 2y = 5 (answer).
Answer:
y = -5x + 6
Step-by-step explanation:
General equation of a line : y = mx + c......where c is intercept
To find m pick any two points..
(-2, 16) and (-1, 11)
Using (y - y¹) / (x - x¹)
(11 - 16) / (-1 - [-2]) = -5 / 1
= -5
To find c sub with any point for (x, y) and m
using (2, -4)
y = mx + c
-4 = -5(2) + c
-4 = -10 + c
6 = c
Input the values of m and c in the general equation without x and y
; y = -5x + 6
EXPLANATION:
-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.
data:
-6 that must be added to a number.
-four times a number that is equal to 4x
-a result that is equal to 50
Now with these data we formulate the equation:
if we solve the equation we have:
