Answer:
Y=-1/2x+4
Step-by-step explanation:
-The slope is -1/2 so you just plug it in where the slope would go with an x in front
-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b
-You can take the provided point at (10,-1) and work out what the intercepts is
-1=-1/2(10)-b
-1=-5-b
4=b
In this question, you're solving for y:
Solve for y:
-3(4y - 7) - y = -2(y - 2)
<em>use the distributive property:</em>
-12y + 21 - y = -2y + 4
<em>combine like terms:</em>
-13y + 21 = -2y + 4
<em>add 2 to both sides</em>
-11y + 21 = 4
<em>subtract 21 from both sides</em>
-11y = -17
<em>divide both sides by -11</em>
y = 17/11
You would check your answer by plugging in 17/11 to the y variables.
