find the formula for the linear function that passes through the point P=(2,-9)and is parallel to the linear function given by the equality: 7x-13y=22
Sol'n:
from the equation, were going to find the the slope of the line.
13y=7x-22, then divide by 13
y=(7/13)x-22/13
from slope-intercept form:y=mx+b, m is the slope
so, m = 7/13
at P(2,-9) w/ m = 7/13
from point-slope form
y-y1=m(x-x1)
y+9=(7/13)(x-2)
13(y+9)=7(x-2)
13y+117=7x-14
7x-13y-131=0 ---answer
^_^
