Answer:

Explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

m = slope

The equation of the given line is

3x+y=10

y = - 3x + c

Comparing it with the slope intercept equation, slope, m = -3

If a line is parallel to another line, the slope of the line is the same with the slope of the given line. This means that the slope of the line passing through the point (-2,4) is -3

We would determine the intercept, c by substituting m = -3, x = -2 and y = 4 into y = mx + c. It becomes

4 = -3 × -2 + c

4 = 6 + c

c = 4 - 6 = - 2

The equation becomes

y = - 3x + - 2
