Answer:

To graph the equation, you need to find the slope and y-intercept.

y = mx + b

⬑[slope-intercept formula; m is the slope, and b is the y-intercept]

y = 4x + −1

⬑[given equation before being simplified]

y = 4x − 1

⬑[given equation]

║m = 4

║b = (0, −1)

Proof:

m = $\frac{rise}{run}$ = $\frac{y_2 - y_1}{x_2 - x_1}$

x₁ = 0

x₂ = 1

y₁ = −1

y₂ = 3

m = $\frac{3 - -1}{1 - 0}$

║m = 4

║b = (0, −1)

[the value for x₁ and y₁ equals the y-intercept: (0, −1)]

How to find variables of these #2 & #3

Lubov Fominskaja [6]

So... hmmm if you check the first picture below, for 2)

we could use the proportions of those small, medium and large similar triangles like $\bf \cfrac{small}{large}\qquad \cfrac{x}{12}=\cfrac{6}{x}\impliedby \textit{solve for "x"}
\\\\\\
\cfrac{small}{large}\qquad \cfrac{z}{18}=\cfrac{6}{z}\impliedby \textit{solve for "z"}
\\\\\\
\cfrac{large}{medium}\qquad \cfrac{y}{12}=\cfrac{18}{y}\impliedby \textit{solve for "y"}$

now.. for 3) will be the second picture below

$\bf \cfrac{large}{medium}\qquad \cfrac{x+10}{2\sqrt{30}}=\cfrac{2\sqrt{30}}{10}\impliedby \textit{solve for "x"}
\\\\\\
\textit{now, because you already know what "x" is, we can use it below}
\\\\\\
\cfrac{large}{small}\qquad \cfrac{z}{x}=\cfrac{x+10}{z}\impliedby \textit{solve for "z"}
\\\\\\
\textit{and let us use "x" again below}
\\\\\\
\cfrac{small}{medium}\qquad \cfrac{y}{10}=\cfrac{x}{y}\impliedby \textit{solve for "y"}$
