For the following system, use the second equation to make a substitution for x in the first equation. x + 3y = 5

x + 7 = 2y

What is the resulting equation?

2 y + 7 + 3 y = 5
2 y - 7 + 3 y = 5
2 y + 2 x + 3 y = 5

Two different linear functions are shown below with two points given from each function. use slope-intercept form or point-slope form to find the equation of each. linear function a points: (–5, –2), (–5, 7) linear function b points: (7, –5), (–2, –5) function a has: the equation of line a is: function b has: the equation of line b is:
