We can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
From the graph, we see the line crosses the y-axis at y = 15. That means the y-intercept is 15, and we have so far y = mx + 15.
Now we need the slope. On the graph we see that for every 3 units up in y, there is 1 unit to the right in x. The slope is 3/1 = 3. m = 3. Now we add the slope to the equation.
y = 3x + 15
Answer: y = 3x + 15
Answer:
a is 67.20 and b is 1267.20
Step-by-step explanation:
first you have to multiply 1200 from 5.6% and you get 67.20 then you have to add 1200 to 67.20 and you get 1267.20
Answer:
85
Step-by-step explanation:
Number of students that checked at least one of the statements means that they checked one or more than one of the statements = 28 + 26 + 14 + 8 + 4 + 3 + 2 = 85
Answer:
x=4
Step-by-step explanation:
The two angles together are complementary, which means they add up to 90 degrees
solving for x:
9x+4x+38=90
9x+4x=13x
13x+38=90
13x+38-38=90-38
13x=90-38
13x=52
x=4
hope this helps ^D^
Answer: slope = 6/15
Step-by-step explanation:
▪︎ Slope = rise / run
▪︎ Rise = y2 - y1
▪︎ Run = x2 - x1
☆ Two points: (-7, -2) and (8, 4)
=> Rise = 4 - (-2) = 4 + 2 = 6
=> Run = 8 - (-7) = 8 + 7 = 15
=> Slope = 6/15
