How do you graph the equation #y=2x-7#?

Answer 1

You need a minimum of three points to plot a straight line. #y=2x-7# the #y# intercept is (0,-7) When #y=0, 2x=7 so => x=3.5# this gives (3.5,0) Then pick another value for #x# and substitute it into the equation to get a #y# value. Plot these three points and draw a straight line through them. You are often given end points for you to plot the graph between so you only draw the line between these points.

To graph the equation (y = 2x - 7), you can start by plotting points on the coordinate plane. Since this equation is in slope-intercept form ((y = mx + b)), where (m) is the slope and (b) is the y-intercept, you know that the y-intercept is at ((0, -7)). From there, you can use the slope of (2) to find another point. For example, if you move one unit to the right (increase (x) by (1)), you move up (2) units (increase (y) by (2)), resulting in the point ((1, -5)). Connect these points with a straight line to graph the equation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
