Answer:
x = 10
Step-by-step explanation:
If f(x) equals 3x-7 and also equals 23, then you can set 3x-7 equal to 23
3x - 7 = 23
3x = 30
x = 10
Answer:
z = -1
Step-by-step explanation:
7 - z / -2 - (-1)
7 - z / -2+1
7 - z / -1
-7 +z = -8
z = -1
to check the work
(-1,-1) (-2,7)
7 + 1 / -2 + 1
8 / -1
= -8
Answer:

Step-by-step explanation:
we have the points
(0,-3),(2,0) and (4,3)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we take
(0,-3),(2,0)
substitute the values in the formula
step 2
Find the equation of the line in slope intercept form

we have
-----> the point (0,-3) is the y-intercept
substitute

The graph in the attached figure
Answer:
That is so easyyyyyyyyy
Step-by-step explanation:
The equation is y = mx + b
y = y coordinate
m = slope
x = x coordinate
b = y- intercept
The Slope is 1
Y-Intercept is -10
So, the equation is y = 1x -10
