Answer:
slope =
Step-by-step explanation:
The slope of a line can be found by identifying two points and the graph and finding the overall change in y over the change in x:
Using the points on the given graph of (-3, 2) and (1, -2):
So, slope =
Answer:
y = - x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 12 = 2x - 3 ( add 12 to both sides )
y = 2x + 9 ← in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, thus
y = - x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = - 1 + c ⇒ c = 3 + 1 = 4
y = - x + 4 ← equation of perpendicular line
