What is the equation of the line that passes through point 5,8 and has a y-intercept of -2

y = 2x - 2

Step-by-step explanation:

y = mx + b

Sub x = 5, y = 8, and b = -2 into the equation.

8 = 5m - 2

Isolate the m-term and solve for m.

8 + 2 = 5m -2 + 2

10 = 5m

Divide both sides by 5 to isolate m.

m = 2

Sub the parameters (m and b) into the template to get your equation.

y = 2x - 2

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
