Answer:
y = 8x + 14
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 )
y = - x + 6 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 8 , then
y = 8x + c ← is the partial equation
To find c substitute (- 3, - 10 ) into the partial equation
- 10 = - 24 + c ⇒ c = - 10 + 24 = 14
y = 8x + 14 ← equation of perpendicular line
Step-by-step explanation:
First thing you do is fine gradient. To do this use the formula:
Then use this formula to find equation of the line:
y = mx + c where m is the gradient
Then Substitute in a point and the calculated gradient value to get c
11 = -0.4 x 3 + c
c = 12.2
Therefore the equation of the line is:
y = -0.4x + 12.2
