$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{-1})\qquad 
(\stackrel{x_2}{3}~,~\stackrel{y_2}{5})
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-(-1)}{3-0}\implies \cfrac{5+1}{3-0}
\\\\\\
\cfrac{6}{3}\implies 2
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-1)=2(x-0)\implies y+1=2x
\\\\\\
y=2x-1$

On three 150-point geography tests, you earned grades of 88%, 94%, and 90%. The ﬁnal test is worth 250 points. What percent do y

Semmy [17]

You must earn 243 points to have earned 93% of all possible points.

We first multiply each percentage on the previous tests by 150:

0.88*150 = 132
0.94*150 = 141
0.9*150 = 135

The total number of points possible is given by adding up the possible points for the three previous tests and the 250 for the last test:
150+150+150+250 = 700

93% of the 700 points would be 0.93(700) = 651 points.

Now we have 132+141+135+x (last test) = 651
408 + x = 651

Subtract 408 from both sides:
408+x-408 = 651-408
x = 243
