Can someone tell me how to figure this question out? i don''t want the answer : ) write the equation of the line containing the point (-2, –7) and having a slope of 3 in slope-intercept form.

y = 3x - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here slope m = 3

y = 3x + c ← is the partial equation

to find c substitute (- 2, - 7 ) into the partial equation

- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1

y = 3x - 1 ← equation in slope- intercept form

you'll have to attache the image of the bar graph in order for us to answer : )
