Step-by-step explanation:
parallel lines have the same gradient..
y=x+7 has a gradient of 1.
If line J which is parallel to k has a gradient of 1 then they are the same.
gradient (m) =<u>∆</u><u>y</u>
∆x
=<u>y- </u><u>-</u><u>1</u><u> </u> = 1
x - - 3
= <u>y </u><u>+</u><u> </u><u>1</u>
x+3
y+1=x+3
y=x +3 +1
y = x + 4(equation for k)
Yes,i think it can,hoped i helped!!!!!!!!!!!
Answer:
y = - 3x + 2
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 )
Rearrange 2y = 14 + x into this form
Divide all terms by 2
y = 7 + x ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 3, hence
y = - 3x + c ← is the partial equation of the perpendicular line
To find c substitute (- 2, 8) into the partial equation
8 = 6 + c ⇒ c = 8 - 6 = 2
y = - 3x + 2 ← equation of perpendicular line
Answer: A
If its around the line and the dots are going the same way than its accurate.
Answer:
Step-by-step explanation:
3(0.3x + 1.3) = 2(0.4x - 0.85)
0.9x + 3.9 = 0.8x - 1.70
0.9x - 0.8x = - 1.70 - 3.9
0.1x = - 5.6
x = - 5.6 / 0.1
x = - 56
