Question

draw the graph for linear equation 7x+5y=35. find the point where this graph meets the line parallel to x axis and 3 units above it.

Answer 1

Answer:

Step-by-step explanation:

We can write as standard form of line equation:

5y = -7x+35;

y = -(7/5)x+7; [y = mx+c, comparing]

Slope of line is -7/5 and y intersect at 7;

A line which is parallel to x axis mean and 3 units above is y = 3 line

Now putting the value of y = 3 in 5y = -7x+35; and calculating x;

5*3 = -7x+35;

15-35 = -7x ;

x = 2.8 and y = 3  is the coordinates of intersection of both lines
