which equation represents a proportional relationship?

y/2 = x + 2/3

y = 3x

xy = 2

y= −3x + 2

Choose the graph that matches the following system of equations: 7x + 2y = −6 6x − 7y = 21 a line includes points negative 2 comma 4 and 0 comma negative 3. a line includes points 6 comma 2 and 0 comma negative 3 a line includes points 0 comma negative 3 and 6 comma 2. a line includes points negative 2 comma 1 and negative 3 comma 4 a line includes points 0 comma negative 3 and negative 1 comma 4. a line includes points 0 comma negative 3 and negative 1 comma 3 a line includes points 0 comma 3 and negative 1 comma negative 3. a line includes points 0 comma negative 3 and negative 2 comma 4.

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
