Answer:
I = $220.50
Step-by-step explanation:
Simple Interest Formula is I = prt
P= Principal $450
R= Rate 0.07
T= Time 7 years
I = (450)(0.07)(7)
I= $220.50

Step-by-step explanation:
Mark brainliest please if my answer is correct thank you and have a nice day
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
![y = \stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{2}}x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}](https://tex.z-dn.net/?f=y%20%3D%20%5Cstackrel%7B%5Cstackrel%7Bm%7D%7B%5Cdownarrow%20%7D%7D%7B%5Ccfrac%7B1%7D%7B2%7D%7Dx%2B6%5Cqquad%20%5Cimpliedby%20%5Cbegin%7Barray%7D%7B%7Cc%7Cll%7D%20%5Ccline%7B1-1%7D%20slope-intercept~form%5C%5C%20%5Ccline%7B1-1%7D%20%5C%5C%20y%3D%5Cunderset%7By-intercept%7D%7B%5Cstackrel%7Bslope%5Cqquad%20%7D%7B%5Cstackrel%7B%5Cdownarrow%20%7D%7Bm%7Dx%2B%5Cunderset%7B%5Cuparrow%20%7D%7Bb%7D%7D%7D%20%5C%5C%5C%5C%20%5Ccline%7B1-1%7D%20%5Cend%7Barray%7D)
so we're really looking for the equation of a line whose slope is 1/2 and passes through (-4 , 1)
![(\stackrel{x_1}{-4}~,~\stackrel{y_1}{1})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{1}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{1}=\stackrel{m}{ \cfrac{1}{2}}(x-\stackrel{x_1}{(-4)}) \\\\\\ y-1=\cfrac{1}{2}(x+4)\implies y-1=\cfrac{1}{2}x+2\implies y=\cfrac{1}{2}x+3](https://tex.z-dn.net/?f=%28%5Cstackrel%7Bx_1%7D%7B-4%7D~%2C~%5Cstackrel%7By_1%7D%7B1%7D%29%5Chspace%7B10em%7D%20%5Cstackrel%7Bslope%7D%7Bm%7D%20~%3D~%20%5Ccfrac%7B1%7D%7B2%7D%20%5C%5C%5C%5C%5C%5C%20%5Cbegin%7Barray%7D%7B%7Cc%7Cll%7D%20%5Ccline%7B1-1%7D%20%5Ctextit%7Bpoint-slope%20form%7D%5C%5C%20%5Ccline%7B1-1%7D%20%5C%5C%20y-y_1%3Dm%28x-x_1%29%20%5C%5C%5C%5C%20%5Ccline%7B1-1%7D%20%5Cend%7Barray%7D%5Cimplies%20y-%5Cstackrel%7By_1%7D%7B1%7D%3D%5Cstackrel%7Bm%7D%7B%20%5Ccfrac%7B1%7D%7B2%7D%7D%28x-%5Cstackrel%7Bx_1%7D%7B%28-4%29%7D%29%20%5C%5C%5C%5C%5C%5C%20y-1%3D%5Ccfrac%7B1%7D%7B2%7D%28x%2B4%29%5Cimplies%20y-1%3D%5Ccfrac%7B1%7D%7B2%7Dx%2B2%5Cimplies%20y%3D%5Ccfrac%7B1%7D%7B2%7Dx%2B3)
