Standard form is y=mx+b slope m is
and the y-intercept, b, is seen by point P to be -4. So
y=x-4
I think that this questions answer is A)1.35
We have to choose two points of this graph:
A(5,0)
B(0,-4)
And we have to compute the slope:
Given two points A(x₁,y₁) and B(x₂,y₂) the slope between these points would be:
m= slope
m=(y₂-y₁)/(x₂-x₁)
In this case:
m=(-4-0)/(0-5)=-4/(-5)=4/5
Answer: the slope would be 4/5 and all of these answer would be wrong.
The slope of any measurement is defined mathematically as the change or the difference of the y values divided by the x or the horizontal values.
In this case it would be 100 m/ 1000m or 1/10.
(3,-4) is your x and y. Plug it in the equation so,
For x,
2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5
For y,
2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1
