Question

What is the equation of the line that passes through the point (-7, 2) and has a slope of -1?

Answer 1

Answer: y= -1x - 5  

Step-by-step explanation:

The equation has to be in slope-intercept form which uses the formula

y=mx+b   where m is the slope and b is the y-intercept.

So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.

the x coordinate is -7  and the y coordinate  is 2

2 = -1(-7) + b    

2 = 7  + b  

-7   -7

b = -5  the y intercept is -5

Now the equation will be y= -1x - 5
