You have the value for y, so you substitute that equation for y, times three because there are three yS.

So you have: 2x + 3y = 10

2x + 3 x 2x + 4 or 2x + 3(3x + 4)

so the answer would be B, 2x + 3(3x + 4)

A line passes through the point (–2, 7) and has a slope of –5. A coordinate plane. What is the value of a if the point (a, 2) is

Nana76 [90]

Y = mx + c

7= (-5)(-2)+ c

7= 10 +c

7-10=c

-3=c

Equation of the line: y = -5x-3

Sub in (a, 2)

2= - 5(a)-3

2+3= -5a

5= - 5a

1= - a

A = -1
