Identify slope of line s: Identify the slope of line s from its equation y=53x+52. Since line t is parallel to line s, it will have the same slope. The slope of line s (and therefore line t) is 53.
Find equation of line t: Use the point-slope form of the equation of a line to find the equation of line t.The point-slope form is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line.Substitute m=53 and the point (2,1) into the equation.
Perform substitution: Perform the substitution: y−1=(53)(x−2).
Distribute slope: Distribute the slope on the right side of the equation: y−1=(53)x−(53)⋅2.
Simplify equation: Simplify the equation: y−1=(53)x−56.
Add 1 to solve for y: Add 1 to both sides of the equation to solve for y: y=(53)x−56+1.
Combine like terms: Combine like terms: y=53x−56+55.
Final equation of line t: Simplify the equation: y=53x−51. This is the equation of line t in slope-intercept form.
