Its early and i want to go back to sleep so pls help

Step-by-step explanation:

equation for a gradient is

m=(y¹-y²)/(x¹-x²)

again the ¹&² are not powers

so (x¹,y¹) and (x²,y²) would be

(-1,6) and (4,-4) respectively

so the gradient would be

(6+4)/(-1-4)

=-2

so the ans is

2=(y¹-y²)/(x¹-x²)

y¹-y²=2(x¹-x²)

y-6=2(x+4)

Note that I put (x, y) into (x¹,y¹)

and (-1,6) into (x²,y²)

(x²,y²) can also be (4,-4), which would lead to the same answer, as theyre the dots on the SAME line

For question 8, try to follow my steps, and figure out the gradient of the graph first, so u can understand what u should do when u see these kinds of questions

(-1,6) and (4,-4)= y - 6 = -2 × (x+1)

(-2,2) and (6,6)= y - 2 = 1/2 × (x+2)

Step-by-step explanation:

Because the point slope formula for equations is y - y = m (x - x1)

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

homozygous. one is homozygous, while two is heterozygous.
