The equations are both in Ax+By=C form. It's very slow and inefficient to start solving the problem by converting the given equations to slope-intercept form, as the other tutor suggested.
Given an equation in Ax+By=C form, any line parallel to it will have an equation of the form Ax+By=N for some N. Then, given a point (x,y) on the line, the value of N is determined by using those x and y values in the general form.
A. parallel to 2x-5y=10 passing through (1,2)
The equation is 2x-5y=N, where N is determined by substituting x=1 and y=2:
N = 2(1)-5(2) = 2-10 = -8
ANSWER: 2x-5y = -8
Put in slope-intercept form by solving for y:
2x-5y = -8
-5y = -2x-8
5y = 2x+8
y = (2/5)x+8/5
Solve the other one in exactly the same way.
