Question

Which of the following is the equation of a line that passes through the points (2,5) and (4,3) ?
A. y=-2x+5
B. y=2x+5
C. y=-x+7
D.y=x+7

Answer 1

worst case, plug in the points to see where they fit

Answer 2

when x=2, which one gives you y=5 ?

if there is more than one, then test out the other point values

Answer 3

Your multiple choice answers are given in slope-intercept form, none of which have equal slope.

I would calculate slope and see which matches your answer.\[m=\frac{y-y_0}{x-x_0}\]
Where m is slope, and the numerator is your change in y, denominator change in x
