Slope itnercept is y=mx+b
ok, let's start with point slope form
y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m
so given point (-3,4) and slope -3/4
y-4=-3/4(x-(-3))
y-4=-3/4(x+3)
distribute to solve for y
y-4=(-3/4)x-9/4
add 4 to both sides
y=(-3/4)x-9/4+4
y=(-3/4)x-9/4+16/4
y=(-3/4)x+7/4

Answer:40 square yards
Step-by-step explanation:
Given
Floor area A=10 square yards
Red tile costs 
per square yards
White tile costs 
per square yards
Total money spent=
on tiles
Suppose red tiles cover an area of 
square yards
So, we can write
Red tiles cover an area of 40 square yards
We are given with two equations to find the values of two variables, hence the problem can be solved.
Adding the two equations:
x + y = 12<u>x - y = 10
</u>2x = 22
<u />x =11
y = 1
