For the equation 9x – 5y = 30, what is:a) the slope and b) the y-intercept.?

Answer 1

9x - 5y = 30
Slope intercept form in y = mx + b where m is the slope (the change in y / change in x) and b is the y intercept (where the graph crosses the y axis).

9x- 5y = 30 Subtract 9x from both sides of the equation
-5y = -9x + 30 Divide both sides by -5
y = (-9/-5)x + 30/(-5)
y= 9/5 x -6

the slope m = 9/5
the y intercept is -6

Answer 2

Rearrange it and make y the priority: 9x - 5y = 30 - 5y = 30 - 9x (substitute the indications): 5y = 9x - 30 (divide by via 5): y = a million.8x - 6 slope (or gradient) = a million.8 ~ that's the quantity in front of x y intercept = -6 ~ while x = 0, y = -6 wish that enables!

Answer 3

a) If you simply rearrange the equation to get it in the form
y=mx+c then m will be the gradient.
So:
9x-5y=30
5y=9x-30
y=(9/5)x-6
Therefore m=9/5, so the slope is 9/5
b) At the y-intercept, the x value is 0, so just sub that in:
y=(9/5)(0) - 6
y=-6
So the y-intercept is (0,-6)

Answer 4

SLOPE
9x-5y=30
slope m=-a/b=-9/-5=9/5
Y-INTERCEPT
put x=0 in the eqn
9(0)-5y=30
-5y=30
y=-6
y-intercept=-6
NOTE:to find x-intercept put y=0

Answer 5

the first thing you should do is transform the equation in y=mx+b

in your equation
9x-5y=30 it will become

-5y=-9x+30 divide both sides by -5 so,

y=9/5-6

so the
a. slope is 9/5 and th y- intercept is -6

i hope i help you in your problem...
goodluck:-)

Answer 6

In order to find the slope, you must set the equation equal to y. In the formula y=mx+b, m is the slope.
To find the y-intercept, you make x=0 and solve for y.

Answer 7

a.12x-3y=30.slope y-intercept b.3y=4.slope. y-intercept c. 9x=18 slope...8 slope of line 5y=3x + 10

Answer 8

5y = 9x - 30
y = (9/5) x - 6

a) slope = 9/5
b) y intercept is y = - 6

Answer 9

a)differentiate w.r.t x:
9-5*dy/dx=0
9=5*dy/dx
dy/dx=9/5=1.8 [i.e de slope]
b)from the given eqn: 5y=9x-30
therefore y=(9x-30)/5
