a line has a slope of "-10/7" and passes through the point (-7,2). what is the equation in slope intercept form

Wrong again!

y = (-10/7) x + b
at( -7,2)
2 = (-10/7)(-7) + b
2 = 10 + b
b = -8

y = (-10/7)x - 8

y = -10/7x + b

b = y - (-10/7x)

b = 2 - (-10/7(-7))

b = 2 + 70/7

b = 24/7

Equation in slope intercept form: y = -10/7x + 24/7
