I would multiply to get rid of the decimals and work with whole numbers.
Since we have numbers that are "hundredths", we would need to multiply every number by 100.
60d + 5e = -450
-12d + 30e = 276 Now that the decimals are gone, if we multiply the second equation by 5 the "d's" will cancel.
60d + 5e = -450
-60d + 150e = 1380
155e = 930
e = 6
Now plug 6 back in for e and solve for d.
60d + 5(6) = -450
60d + 30 = -450
60d = -480
d = -8
(-8, 6)
If you'd rather work it with decimals just let me know.
The point-slope form:
We have the point 
and the slope 
.
Substitute:
Step-by-step explanation:
A trinomial is an expression that has three terms.
Square trinomial
A square trinomial is simply a perfect square trinomial, and it is represented as:
\mathbf{a^2 + 2ab + b^2 = (a + b)^2}a2+2ab+b2=(a+b)2
Difference of square binomials
This is easily identified because, the terms of the square binomials are perfect squares.
The difference of square binomials is represented as:
\mathbf{a^2 - b^2 = (a + b)(a - b)}a2−b2=(a+b)(a−b)
Sums and difference of cubes
When cubes are added or subtracted, they can be expressed using the following
\mathbf{a^3 + b^3 = (a + b)(a^2 - ab + b^2)}a3+b3=(a+b)(a2−ab+b2) --- sum of cubes
\mathbf{a^3 - b^3 = (a - b)(a^2 + ab + b^2)}a3−b3=(a−b)(a2+ab+b2) --- difference of cubes
