From the slope our equation so far is
y = -4/5x + B
Now we find B
-------------------------
To find be all we have to is substitute (-5,-4) for x and y in <span>3x + 5y = 15
</span>(-4) - (-4/5)( -5) = b
-8 = b
---------------------------------
So your equation would be y = -4/5x - 8
Answer:
You have to graph and label the points
Step-by-step explanation:
3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle
-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4
2 is just a horizontal line starting at (closed circle) 4, it is greater than also.
If you don't understand the the constants (the numbers on their own) just a vertical translation.
If the cross either the x or y axis, you have to find that too, im pretty sure.
To find the y axis intercept, make x = 0 and solve for y
and to find the x axis intercept, make y = 0 and solve for x
Answer:
x = 23
Step-by-step explanation:
2x -3 + 47 = 90
2x = 46
x = 23
