Question

A line passes through the point (-6, 4) and has a slope of -2.

Write an equation in slope-intercept form for this line.

Answer 1

y= -2x - 8

Explanation:

make use of the formula y=mx + c

where,

y is a point

m is the slope

x is an x coordinate and,

c is a number to be found

(-6, 4)

4= -2(-6) + c

make c subject of formula

c= 4 - 12

= -8

therefore the equation is y= -2x - 8
