Answer:
Step-by-step explanation:
(-2, -3) (-1, -1)
(-1 + 3)/(-1 + 2)= 2/1 = 2
y + 3 = 2(x + 2)
y + 3= 2x + 4
y = 2x + 1
220c-287=103
add 287 to both sides
220c=390
divide both sides by 220
c=1.77
First find the slope of this new line; it's the same as the slope of the "given line," which you unfortunately have not yet given. Let's call that slope "m."
Then, the equation in point-slope form of the new line is
y - (-1) = m(x - [-1]), or y+1 = m(x+1)
Please go back to the original question, obtain the slope of the "given line," and substitute that value for m in y+1 = m(x+1).
Answer:
y = - 8
Step-by-step explanation:
The given line passes through (-4, 4) and (4, -2)
The slope of this line will be given by: Change in y ÷ change in x
Slope = = =
The slope of the given line times the slope of the perpendicular line = -1
Let's say the slope of the perpendicular line is p
Then, × p = -1
p = -1 ÷ =
The perpendicular line passes through point (6, 0)
Taking another point (x, y) on the perpendicular line;
=
Cross multiplying this gives the equation of the perpendicular line to be:
y = - 8
One 8 is in the tens place while one is in the hundreds place or 10(80) compared to 100 (800).
