The equation of line CD is y = −2x − 2. Write an equation of a line parallel to line CD in slope-intercept form that contains point (4, 5).
y = −2x + 13
y = negative 1 over 2 x + 7
y = negative 1 over 2 x + 3
y = −2x − 3

ok
well a line that is parallel to y = -2x -2 will have the same slope
The -2x indicates that the slope is -2.
OpenStudy (anonymous):
Yes
OpenStudy (welshfella):
To find if the point (4,5) is on the line you plug in x = 4 and y = 5 into the equation and see if it fits.
OpenStudy (anonymous):
so the equation would be 2(x-4) = y-5
OpenStudy (anonymous):
distribute it and get 2x-8=y-5

the equATION WOULD BE y = -2x + a
where a is a number to be found
OpenStudy (anonymous):
opposite operations and get -2x +8=y-5
OpenStudy (anonymous):
i forgot that the slope was -2
OpenStudy (anonymous):
not 2
OpenStudy (welshfella):
substituting
5 = -2(4) + 13
LHS = 5
RHS = -8+13 = 5
so A is the correct equatuon
