Answer:
y =-5x-17
Step-by-step explanation:
Slode-intercept is
y = mx + c
The first step is to find the slope, that is the m
To do that, use this formula
Y2 - y1
------------
X2- x1
And u will get - 5
Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs
So let's say I chose (-4, 3)
So x = - 4, y = 3
y=mx +c
3= - 5(-4) +c
C = - 17
Therefore your end product will be
y = - 5x - 17
Answer:
25x - 45 = 5(5x - 9)
Step-by-step explanation:
Find the greatest common factor (GCF) of 25 and 45.
You can do this several ways, but one way is to list all the factors of both numbers and find the greatest common one:
Factors of 25: 1, 5, 25
Factors of 45: 1, 3, 5, 9, 15, 45
Therefore, 25 and 45 have 2 common factors: 1 and 5
So the greatest common factors is 5
25x - 45 = 5(ax - b)
To find the value of a, simply divide 25 by 5: 25 ÷ 5 = 5
To find the value of b, divide 45 by 5: 45 ÷ 5 = 9
25x - 45 = 5(5x - 9)
