Step-by-step explanation:
x is the independent variable
y is the dependent variable
Answer:
hi :]
Step-by-step explanation:
y = 8-5x
Step-by-step explanation:
When two lines are parallel, it means their gradients are the same.
from the given equation
y = 9-5x
and comparing with the general equation of a line
y = mx+c, where m is the gradient, and c is the <em>y-intercept, </em>
m = -5
you can form a line parallel to that using the points (0,8)
(y-8)/(x-0)= -5
this would give you
y = 8-5x
Answer:
15x + 9
Step-by-step explanation:
9(3x + 8) – 3(4x + 21)
Multiply
27x + 72 - 12x - 63
Combined like terms
27x - 12x = 15x 72 - 63 = 9
15x + 9
You need to use y=mx+c to answer this so basically
gradient/slope (m) is 1.5 and the y-intercept (c) is -2
Hope this helps :)
