There is a line whose slope is 1 and whose y-intercept is -10 .what is its equation in slope-intercept form?

In y = mx + b form, the slope is in the m position and the y int is in the b position

y = mx + b
slope(m) = 1
y int (b) = -10
now sub
y = 1x + (-10) which can be written as : y = x - 10 <==
