Directly proportional means if x has a certain value, y should have the same value. but here in the graph, when x is 0, y has a value greater than 0. for x and y to be directly proportional, the line should go through 0.
You can't simplify this problem any further because there are no more like terms
Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.
