I need to find the slope, vertical intercept and horizontal intercept of these 3 linear functions:

Bumek [7]

These are in y=mx+b form where m=slope
sometimes b=0

vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is

y=5x-15
slope=5
y-intercept=-15
x-intercept=3

y=7-x
this can be written as
y=-1x+7
slope=-1
y-intercept=7
x-intercept=7

4x=2y=12
we must get it into slope intercept form
divide the whole thing by 2x=y=12
we can disregard the 12 and get
2x=y or y=2x+0
slope=2
y-intercept=0
x-intercept=0

a line goes through the point(6,-2)and has a slope of -3 what is the value of a if the point (a,7) lies on the line

yaroslaw [1]

Answer:

The value of a is "3", to complete the coordinate point (3,7) on the line.

Step-by-step explanation:

We are given the slope of the line, and also one point through which the line passes. Therefore, we can find the actual equation of the line by using the slope-point form of the line:

$y-y_0=m(x-x_0)\\y-(-2)=(-3)(x-6)\\y+2=-3x+18\\y=-3x+18-2\\y=-3x+16$

Now, we need to find which value of "x" renders a y-value of "7", to complete the coordinate pair (a, 7) as requested. Therefore, we ask for the y-value in the previous equation to be "7", and solve for its associated x-value:

$y=-3x+16\\7=-3x+16\\7-16=-3x\\-9=-3x\\x=\frac{-9}{-3} \\x=3$

Therefore, x = 3

Two equations are given below:

Evgesh-ka [11]

The solution to the set of equations is (0,2).

Reasoning:

m + 4n = 8 -> 0 + 4(2) = 8

m = n - 2 -> 0 = 2 - 2
