&({{ 0}}\quad ,&{{ 0}})\quad 
% (c,d)

\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{4-0}{1-0}\implies 4$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-0=4(x-0)\implies \boxed{y=4x}

You guys are Smart, Answer me this. But I need It fast-

miss Akunina [59]

Answer:

E = 58

F = 32

G = 90

Step-by-step explanation:

3x + 31 + 5x -13 + 90 = 180

3x + 31 + 5x -13 = 90

8x = 90 - 31 + 13

8x = 72

x = 72 / 8

x = 9

E = 3(9) + 31 = 27+31 = 58

F = 5(9)-13 = 45 - 13 = 32

G = 90
