3 burritos and 4 tacos cost 11.33 3b + 4t = 11.33 
<span>9 burritos and 5 tacos cost 23.56 9b + 5t = 23.56 </span>
<span>To solve: multiply top equation by 3. </span>
<span>3(3b + 4t = 11.33) becomes 9b + 12t = 33.99 </span>
<span>9b + 5t = 23.56 stays as is 9b + 5t = 23.56 </span>
<span>Now subtract the second equation from the first and you will get </span>
<span>7t = 10.43 which you can solve by dividing both sides by 7 to get t = 1.49 so a taco costs $1.49. </span>
<span>Now replace a t in either equation with 1.49 so 3b + 4t = 11.33 becomes 3b +4(1.49) = 11.33 or 3b + 5.96 = 11.33. Now subtract 5.96 from each side leaving 3b = 5.37 and finally divide both sides by 3 to get b = 1.79 so a burrito costs $1.79 </span>

<span>Problem Two: </span>
<span>3 brass and 10 steel costs $48 3b + 10s = 48 </span>
<span>7 brass and 4 steel costs $54 7b + 4s = 54 </span>
<span>To solve: multiply top equation by 2 and the bottom equation by 5 so the number of s's will be equal </span>
<span>2(3b + 10s = 48) becomes 6b + 20s = 96 </span>
<span>5(7b + 4s = 54) becomes 35 b + 20s = 270 </span>
<span>Now subtract the top equation from the bottom equation and you will get 29b = 174. Divide both sides by 29 to get b = 6. </span>
<span>Now replace the b of either original equations with the 6 (say the top equation) to get 3(6) + 10S = 48 or written another way, </span>
<span>10s + 18 = 48. Now subtract 18 from both sides to get 10s = 30 and then divide both sides by 10 to get s = 3. </span>
<span>b=6 and s=3 so each brass part is $6 and each steel part is $3.</span>

Graph the line by plotting y=x+8​
Zarrin [17]

The equation y = x + 8 uses the slope intercept form

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

In this case

y = 1x + 8

m = 1

y = x + 8

b = 8 OR y-intercept of this line is (0, 8)

You can plot the point (0, 8) on a graph. Then to find the next point you will rise up 1 and over right 1 (this is the slope). You can find another point after that by going down one and left one from the point (0, 8)

The graph should look like the one in the image below

Hope this helped! Let me know if you have any further questions
