Drag equations to each row to show why the equation of a straight line is y = 2x + 5, where 2 is the slope and 5 is the y-intercept. Help

y-5/x =2/1 for the two triangles on the graph are similar

Y-5=2x for multiple both sides by x

Y=2x+5 for add 5 to both sides

Step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
