Answer:

To graph an inequality, treat the <, ≤, >, or ≥ sign as an = sign, and graph the equation. ... If the inequality is ≤ or ≥, graph the equation as a solid line. This line divides the xy- plane into two regions: a region that satisfies the inequality, and a region that does not. Next, pick a point not on the line.

Slope of (1,3) and (4,9)

elena-s [515]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (4, 9)

m = $\frac{9-3}{4-1}$ = $\frac{6}{3}$ = 2

How would you solve for the question below???<br> step by step please and thanks.

Airida [17]

Combine the two equations in the right amounts to eliminate y :

-2 (2x + 3y) + (3x + 6y) = -2 (17) + 30

-4x - 6y + 3x + 6y = -34 + 30

-x = -4

x = 4

Solve for y :

2x + 3y = 17

8 + 3y = 17

3y = 9

y = 3
