The first integer is going to be x and the second one is going to be y.
We now turn the clues into equations:
x = y - 5
xy = 84
The substitution method:
(y - 5)y = 84
y^2 - 5y - 84 = 0
(y+7)(y-12) = 0
y = -7, 12.
If y = -7, then x = -12.
If y = 12, then x = 7
I believe the answer to your question would be x = -y + 2
Answer:
Can i see a pic of the shaded part?
Step-by-step explanation:
Answer:
(5,-3)
Step-by-step explanation:
y+3 = 3x-15
y= -2x + 7
plulg y in
-2x+7+3 = 3x-15
combine like terms
-2x+10 = 3x-15
add 2x to both sides and add 15 to both
5x=25
x=5
y=-2(5) + 7
y= -10 + 7
y= -3
(5,-3)
I see lattice points (0,-3) and (4,4) so slope is change in y over change in x,
m = (4--3)/(4-0) = 7/4.
The y intercept is when x=0, so (0,-3), often just called -3.
So the equation is
y = (7/4) x - 3
Answer: Slope 7/4, y intercept -3
