Answer:
y=3x-5 is a linear equation
Answer:
2
Step-by-step explanation:
There are four giraffes that equal 32. That means the four of them equal 32, and since they are all giraffes, they are the same amount.
32/4 = 8
Girrafe = 8
Two tigers times a giraffe equals 32. We already know that a girrafe equals 8.
32/8 = 4.
Therefore the two tigers equal 4. Since there are two tigers, and they equal 4, each tiger equals 2.
Now we know girrafes equal 8, and tigers equal 2.
A girrafe - A tiger x 3 = 2
PEMDAS says that you multiply first. So 2 x 3 equals 6. Take away 6 from 8 and you get 2.
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1
So we first need to find the slope of the reference line.
m=(y2-y1)/(x2-x1)=(7-2)/(-1--5)=5/4
So the perpendicular line will have a slope of:
5m/4=-1
m=-4/5
So our perpendicular line so far is:
y=-4x/5+b, now we can use point (3,-1) to solve for the y-intercept, "b"
-1=-4(3)/5+b
-1=-12/5+b
-5/5+12/5=b
7/5=b
So the line is:
y=-4x/5+7/5 or more neatly
y=(-4x+7)/5
y=-0.8x+1.4
