Answer:
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0).
First, we must find the slope (<em>m</em>).
where two points that fall on the line are and
Two points that are highlighted for us on the graph are (-3,-2) and (5,4). Plug these into the equation:
Therefore, the slope of the line is 3/4. Plug this into :
Now, to find the y-intercept (<em>b</em>), our first resort would be to find it on the graph. However, on the graph, it appears ambiguous. So, we must solve it algebraically.
Plug in the point (5,4) and solve for <em>b</em>:
Therefore, the y-intercept is . Plug this back into :
I hope this helps!
Its udefined because the question asked describe the line of a slope, now its not negative or positive because there is no change. Its undefined because its a line, going vertical way
Answer:
it'll be 65
Step-by-step explanation:
65 + 72 + 98 + 85 is 320 and that divided by 4 is 80

Answer: c= 0.79p
Step-by-step explanation:
Divide each cost by the number of pens it have to find the constant change value.
3.95/5 = 0.79
7.90/10= 0 .79
11.85/15 = 0.79
15.80 / 20 = 0.79
Since the constant change is 0.79 which means that for each pen it will cost you $0.79, then the equation will be c= $0.79p where c is the cost and p is the number of pens.
