So y=mx+b
b is the y-intercept or where they cross the y-axis so just set a y-intercept and change the slope
so if y-intercept is 7
y=3x+7
y=2x+7
y=8x+7
y=-1/4x+7
and so on
3x-2
-(-5x+7)
☝️this is your equation
distribute your subtraction sign to -5x+7 and you get
3x-2
+5x-7
add everything together and you end up with
8x-9
This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.
The x-coordinate of the point(s) of intersection is the solution.
_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)
Y depends on x. And x are the real numbers.
Hope this helps!
