On solving the provided question, by substitution method we got that y=1.43 and x=o.65
<h3>What is substitution method?</h3>
To solve systems of linear equations, use the algebraic technique of substitution. The name of the technique implies that it involves substituting the values of variables from one equation into another.
x=cakes , y=donuts
3x+6y=$10.14 ------ eqt.1
4x+4y=$8.32 ------ eqt.2
solve eqt.1 for "y"
y=1.43
x=o.65

Answer:
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0).
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two points that fall on the line are and
Plug in the given points (4, -6) and (0, 2):
Therefore, the slope of the line is -2. Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
The y-intercept occurs when x=0. We are given that (0,2) falls on the line, so therefore, 2 is the y-intercept. Plug this into :
I hope this helps!

Answer:
y -4 = -2(x -3)
Step-by-step explanation:
The point-slope form of an equation for a line through point (h, k) with slope m is ...
y -k = m(x -h)
You have (h, k) = (3, 4) and m = -2, so your equation is ...
y -4 = -2(x -3)
