When do I use elimination and when do I use substitution?

1 answer:

Elimination is used when there is a common factor between the two equations. Substitution is used in cases where finding a common term just isn’t possible, or too complicated.

Answer:

$\frac{2}{3}$

Step-by-step explanation:

Using standard form (Ax+By=C) equals $\frac{a}{b}$

2x-3b=c

$\frac{2}{-3}$

now simplify $\frac{2}{3}$

Write any equation in slope intercept form that has a slope of3/2 and passes through (2,7)

Paha777 [63]

slope intercept form - (y = mx + b)

slope (m) is (3/2) So, y = 3/2x + b

To find b you plug in the x and y value (2,7)
7 = 3/2 × 2 + b

Isolate x on one side by finding the value of 3/2 × 2 which is 3.

Subtract 3 from both sides which leaves you with 4 = b, so the value of b is 4

Now the slope intercept form is (y = 3/2x + 4)
