Mandy used the graph to write the equation of the line it represents. She took these steps.

1. y−intercept = (0, 2)

2. Slope =
rise
run
=
− 2
4
= −
1
2

3. Substituting values into y = mx + b

y = x +
On a coordinate plane, a line goes through points (0, 2) and (4, 0). The run = 4 and the rise = negative 2.

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
