Step-by-step explanation:
-3x - 7y = -63
-(3x + 7y) = -63
3x + 7y = -63/-1
3x + 7y = 63
Value of x
3x + 7y = 63
3x = 63 - 7y
x = (63 - 7y)/3
Value of y
3x + 7y = 63
7y = 63 - 3x
y = (63 - 3x)/7
slope = - 
using the points on the line ( - 4, 5 ) and ( 1, - 4 )
slope = ( - 4 - 5 )/( 1 - ( - 4 )) = - 
Answer:
see the attached for the table and rules
Step-by-step explanation:
a) A graph of the given points shows they lie on the same line, one with a slope of 3 and a y-intercept of 2. Thus the rule is ...
y = 3x +2
see the attachment for table values
__
b) The ratios of given points are all the same: y/x = 5/2, so that is the constant of proportionality:
y = (5/2)x
