Use the 2 points and use the formula
to get slope
and you get a slope of -2
for the second question its non of the above? i think the x intercept is 0.6666. if you're talking about y intercept then its -5
Answer:
35 minutes, 17 mm
Step-by-step explanation:
Using the location on the graph, we can determine the millimeters of rain (y) along with the duration of the storm (x).
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)
To find "m", you can use the slope formula and plug in the two points:
(2,3) = (x₁ , y₁)
(0,9) = (x₂ , y₂)
m = -3
y = -3x + b
To find "b", you can plug in one of the points into the equation (however they already gave you the y-intercept (0,9) or 9)
(2,3)
y = -3x + b
3 = -3(2) + b
3 = -6 + b
9 = b
y = -3x + 9
Hey there,
x= (56×20)/14
x=80
Answer: 9x2 + 15x -6
Step-by-step explanation: ( 3x + 6) (3x -1)
9x2 - 3x + 18x - 6
= 9x2 + 15x -6
