Answer: Y-intercept is (0,-1/7) and the slope is -3/7
Step-by-step explanation:
State the slope and the y-intercept for the graph of each
equation y= -3/7x–1/7
To find the y-intercept,
you plug in 0 in for x for y= -3/7x–1/7
y=-3/7(0)-1/7
y=0-1/7
y=-1/7
The y-intercept is (0,-1/7)
To find the slope, you first check that the equation is in the form of y=mx+b
y= -3/7x–1/7 is in the from of y=mx +b.
The m is the slope
hence, in y= -3/7x–1/7 the slope is -3/7
Factor the numerator and denominator then simplify.
6x^2 - 54 6(x^2 - 9) 6(x + 3)(x - 3) 6(x - 3)
-------------- = ------------- = ------------------ = ------------
5x^2 + 15x 5x(x + 3) 5x(x + 3) 5x
6(x - 3)
----------
5x
