Your turn:
1. Find the equation of a line passing through the points (-1, 7) and (8, -2)
a. what do I know?
Given: 2 points
(x1 y1) (x2 y2)
b. the form i will use is
y2 - y1 = y2 - y1
________ (x - x1)
x2 - x1
c.
y - 7 = (-2) -7
_________ (x + 1)
8 - (-1)
y - 7 = -9
_____ (x + 1)
9
y - 7 = -x - 1
x + y = -1 + 7
x + y = 6
2. Write the equation of a line with a slope of 5 and a y-intercept of (0, -7)
a. what do I know?
m of 5
(x1 y1)
b. the form i will use is...
y - y1 = m
(x - x1)
c.
y + 7 = 5 ( x - 0)
_______________
y + 7 = 5x
7= 5x - y
Step-by-step explanation:
pakisama nalang yung line :) hehe salmat
#1. What do i know?
m of 2
(x1 y1)
#2. The form i will use is...
y - y1 = m
(x - x1)
c.
y - 4 = 2 (x - 2)
______________
y - 4 = 2x - 4
+4 - 4= 2x - y
