The equation of a line is:
y = mx + c
The m is the gradient of the line, and the c is the y-intercept of the line
That means that the y-intercept of [y = -4x + 3] is 3
and the y-intercept of [y = -4x + 4] is 4
So the distance between the two y-intercepts is:
4 - 3 = <u>1</u>
Answer:
It takes 32 Minutes for 12 people to paint 12 walls
Step-by-step explanation:
If it takes 8 people 32 minutes to paint 8 walls, then that means each person takes 32 minutes to paint 1 wall. With that being said, If you have 12 people painting 12 walls, It will take 32 minutes for all 12 walls to be painted.
Hope this helps!
Hello,
Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2
Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4
One other way:
y=9-1/2 x²
y'=-x
gradient 1=-(-2)=2 for point (-2,7)
gradient 2=-(4)=-4 for point(4,1)
Answer:
sometimes
