Question

How do we do with this formula? Help me with A pls​

Answer 1

find all the equation placing each one

Explanation:

for eg in no a

gradient is 2

point is (4,1)

so the point (4,1) is (x1,y1)

using formula

y-y1=m(x-x1)

y-1=2(x-4)

y-1=2x-8

therefore 2x-y-7=0 is the required equation

now do all of the above like this

Answer 2

Gradient is the slope, which is the letter m in the equation.

The point is written as (x1, y1) so replace x1 and y1 in the equation with the numbers in the given point.

A would be y - 1= 2(x-4)

B: y +5 = 5(x-2)

C: y-1= -3(x+1)

D: y -6 = 1/2(x-1)

E: y +1/4 = -2(x-3:4)

F: y+7 = -1/5(x+ 3)
