Which equation matches the graph? (Click me to see the image)
y=−41x+2
y=41x+2
y=x+4
y=4x+2
How would you write the equation of a line with a slope of 2/3 and a y-intercept of -3
y=32−3
y=32x−3
y=32x+3
Write the slope-intercept form of the line shown in the graph.
y = 4/5 x − 1
y = −x − 4/5
y = x − 4/5
y = −4/5 x − 1
What are the TWO important characteristics a graph needs to have to be considered Proportional?
It needs to be a straight line
The line needs to pass through the origin
The line CANNOT pass through the origin
The line CANNOT be a straight line.
Is this graph proportional or non-proportional?
Proportional
Non-Proportional
This graph is NOT proportional. What would MAKE it be proportional? (What requirement is it missing?)
The line needs to be straighter.
The line needs to start at the origin (0,0)
