Answer:
Slope-intercept form of line t is
y = 2x - 5.
Step-by-step explanation:
Line s is y + 3 = 2(x + 10)
This is in point slope form where 2 is the slope so line t also has slope 2 because the 2 lines are parallel,
and can be written as y - y1 = 2(x - x1) where (x1, y1) is a point on line t.
So we have x1 = 6 and y1 = 7, so:
Line t has equation y - 7 = 2(x - 6)
Convert this to slope-intercept form:
y = 2(x - 6) + 7
y = 2x - 12 + 7
y = 2x - 5.
