The slope is the change in y over the change in x, so it's (4-2)/(6-7)=2/-1=-2. Point slope form is y<span> – </span>y1<span> = </span>m(x<span> – </span>x1<span>), so we can plug in a point (6,4) to get
y-6=-2(x-4)</span>
The number would be 18.
Half of 18 = 9
Two thirds of 18 = 12
9 + 12 = 21
Answer:
y = - 1
Step-by-step explanation:
The 2 lines are equal at the point of intersection
The point of intersection is (2, - 1 ) with y = - 1
Angle 1 = 180-10= 170 degrees, and the relationship is called supplementary angles
