Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
If m > 0 , then line slopes upwards from left to right
If m < 0 , then line slopes downwards from left to right
y = 3x - 2
has m > 0 and c = - 2 , thus line slopes upwards crossing the y- axis at - 2
y = - 2x + 3
has m < 0 and c = 3, thus line slopes downwards crossing the y- axis at 3
on the graph this is the lower blue line and the red line
the solution to the system is at the point of intersection of the 2 lines
This is at point D
Fill in the slope and that point in y=mx+b
-14=6(-12) + b
-14= -72 + b
b= 58
Y=6x + 58
Answer:
y=10
Step-by-step explanation:
y/5+7=9
y/5=9-7
y/5=2
y=2*5
y=10
Answer:
72
Step-by-step explanation:
I have a weird way of doing it
so if 18 is 25%
18+18=36
then 36 would be 50%
36+36=72
so then 72 would be 100%
72*.25=18
Y = -5x +18
x can be any number, y can be change due to x value
