3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
Part A: The slope of the linear function, f(x), equals 8, while the slope of g(x) = 3x - 2 equals 3.
--- Steps ---
Linear Function:
y2 - y1 -1 + 9
---------- = ---------- = 8
x2 - x2 0 + 1
g(x) = 3x - 2
Slope Intercept Form ~ y=mx+b
m is the slope, so in this equation, the slope is 3.
Part B: The function g(x) = 3x - 2 has a greater y intercept.
How to find the y intercepts:
g(x) = 3x - 2
The y intercept here is 2 because in slope intercept form, m is the slope and b is the y intercept: y =mx+b
F(x) table of values:
The y intercept here is -1. I found my answer by plotting all of the points on a coordinate grid. When you plot (0, -1), you will see that there is a spot where the line hits the y axis. That point is called the y intercept. So your y - value is -1, making the y intercept -1 also.
I hope this helps you out.
