alternate angle,
The slope and y-intercept of a linear equation can be identified directly from the graph. In this case, the y-intercept is 9 and the slope is 3, making the equation of the line y = 3x + 9.
In Mathematics, we often work with linear equations, which can be represented graphically as a straight line. The slope and y-intercept are two key aspects of this equation and can be obtained directly from the graph. Specifically for problem 6, your line graph has x on the horizontal axis and y on the vertical axis, and intersects the y-axis at the point (0,9). This tells us that the y-intercept (represented by b in the equation) is 9. Furthermore, the slope (represented by m in the equation) is the rise over run, or change in y over change in x. In this case, for every 1 unit increase in x, y increases by 3 units, so the slope is 3. Therefore, the standard form of the line equation would be "y = 3x + 9."

Answer:
d = 0.7*t
Step-by-step explanation:
Given data,
Time Distance
10 7
15 10.5
20 14
From analysis,
1) d1/t1 = 7/10 = 0.7
2) d2/t2 = 15/20 = 0.7
3) d3/t3 = 14/20 = 0.7
It can be analysed from the figure that, at every point d/t = 0.7
Therefore, the relationship between t and d is
d = 0.7*t
or
t = d/0.7
Answer:
d=0.7t
