Answer:
y=x-5
Step-by-step explanation:
the y intercept is -5 and slope is 1
Because 4x2 = 8, so 4x7=28, then you times 28 by 2 which equals 56 and 8x7=56
Answer:
y = 14.5
Step-by-step explanation:
given that y varies directly as x
mathematically,
y ∝ x
y = kx .............................................. where k is the constant of proportionality.
k = y /x
given that
y = 79
x = 49
k = 79/49
k = 1.61
to find y when x = 9
from
y = kx
y = 1.61 × 9
y = 14.5
therefore the value of y when x = 9 in ths variation is evaluated to be equals to 14.5
