You have to find the reciprocal of the gradient - 1/2
And to do that just flip the sign and fraction:
-1/2
1/2
2/1
So the answer is,
Y = 2x + 11
X=0 because when you have something to the power of zero your answer is 1.
x=0 since 1 to the power of zero equals 1.
hope im not too late
Answer:
A
Step-by-step explanation:
coplanar means 3 points in a plane. D is collinear and the others are just wrong. Brainliest here !!
X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)
