You calculate it by taking the change in y's over the change in x's. So (y1-y2)/(x1-x2). You get the equation (-5 - 3)/(5 - 7) which equals 4. 4 is the slope.
Answer:
144500
Step-by-step explanation:
(1.7 x 10^4) x (8.5 x 10^-2)
= (1.7 x 10000) x (8.5 x 0.01)
=( 17/10 x 10000/1) x (17/2 x 1/100)
=17000/1 x 17/200
=289000/2
=1445000
Answer:
I cannot give you a full answer because it's missing crucial information- the points on the graph. However, I can give you insight!
Suppose one point is (2,3), if you want to scale it by a factor of 3, you would simply multiply both variables by 3. So the new point would be (6,9).
If you want to scale (4,7) by factor of 2, you would multiply the 4 and the 7 with 2. The new point would be (8,14).
14.35/5= $2.85 per pane of glass
2.85*2= $5.70
Perpendicular has slope that multiplies to -1
y=mx+b
m=slope
y=-1x+11
-1 times what=-1?
what=1
y=x+b
find b
given
(-2,3)
(x,y)
inpus -2 for x and 3 for y
solve for b
3=1(-2)+b
3=-2+b
add 2 to both sides
5=b
y=x+5 is equation
