Answer:
4x + 3y = -3.
Step-by-step explanation:
First substitute into the point-slope form:
y - y1 = m(x - x1):
y - 3 = (-4/3)(x - -3)
y - 3 = (-4/3)(x + 3)
y - 3 = -4/3 x - 4
y = -4/3 x - 4 + 3
y = -4/3x - 1 Multiply through be 3:
3y = -4x - 3
4x + 3y = -3 (answer).
X is equivalent to 200. (credit to suspho)
Answer:
C = (5/9F) - (160/9)
Step-by-step explanation:
F = 9/5C + 32
F - 32 = 9/5 C
C = 5/9 (F-32)
C = (5/9F) - (160/9)
To solve this problem, we can begin by analyzing the graph and then eliminating incorrect answers. By looking at the graph, we can see that it has a positive correlation (the graph is increasing from left to right), which tells us that it has a positive slope. Using this knowledge, we can eliminate answer choices C and D, which both suggest equations with a negative slope (which would mean that the line was decreasing from left to right).
Next, we must analyze the slope. Answer A suggests that the slope is 3/2, meaning that the line rises 3 units for every 2 units it goes across. Answer B suggests that the slope is 1/2, meaning that the line rises 1 unit for every 2 units that it goes across. If we look at the graph, let's say at the point (0,3), the next closest point is 3 units up and 2 units across, which lets us know that the slope is positive 3/2.
Therefore, your answer is A. y = 3/2x + 3 (which is confirmed by the point we recognized, (0,3), which is the y-intercept of the equation).
Hope this helps!
