Answer:
Part A: y = 4.5x + 22
Part B: 31 inches
Step-by-step explanation:
Part A:
the y-intercept appear to be at 22
the slope can be found by using the points (0, 22) and (4, 39)
m = <u>39 - 22</u>
4 - 0
m = 17 / 4 = 4.3 and this is close to 4.5
Part B:
plug in 2 for 'x' in the equation: y = 4.5x + 22
y = 4.5(2) + 22
y = 9 + 22
y = 31
Answer:
The slope is 1/4 so the slope intercept form is y=1/4+3
Step-by-step explanation:
To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.
