How do you graph y=7/2x-2

RoseWind [281]

You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule

ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)

Or you can put the rule in a graphing calculator and check the points from there

Write an equation for the line that is parallel to y = −2x and passes through the point (0,7).

Answer:

B. $\displaystyle y = -2x + 7$

Step-by-step explanation:

The y-intercept is given to us, which is $\displaystyle [0, 7],$ and Parallel Lines have SIMILAR RATE OF CHANGES [SLOPES], so −2 remains the way it is.
