Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
Answer:
16
Step-by-step explanation:
8(19-17)=8(2)=16
The equation of the given line is y = 5/6x - 2
The standard equation of a line in slope-intercept form is expressed as
y = mx + b
m is the slope of the line
b is the y-intercept
Using the coordinate point (0, -2) and (-6, 3)
Slope m = 3-(-2)/-6-0
m = 5/6
Since the line cuts the y-axis at y = -2, hence the y-intercept is -2.
Find the equation of a line;
y = mx + b
y = 5/6x + (-2)
y = 5/6x - 2
Hence the equation of the given line is y = 5/6x - 2
