Slope is the change in the y value over the change in the x value. The y value goes from 4 to -3. The change would be -7. X goes from 0 to 2, so the x change is 2. The slope is then (-7/2), or answer c

3) y = mx + b (m is the slope and b is the y-intercept)
so y = -2x + 3
Answer:
the desired equation is y = -3x + 6.
Step-by-step explanation:
1) Rewrite x - 3y = 5 in slope-intercept form: x - 5 = 3y, or y = (1/3)(x - 5)
2) Identify the slope of the given line. It is (1/3).
3) Find the slope of a line perpendicular to this one. It is the negative reciprocal of (1/3), or -3.
4) Use the slope-intercept form of the equation of a straight line, y = mx + b, to determine the b value and thus the equation of the perpendicular line:
6 = -3(0) + b. Then b = 6, and the desired equation is y = -3x + 6.
