What is the equation of a line that passes through the point (1, 3) and is parallel to a line with a slope of -2?
1 answer:
Answer:
y =-2x+5.
Step-by-step explanation:
lines that are parallel have the same slopes. Let us plug in our slope and given point into the slope-intercept form y = mx + b. Remember, (1, 3) = (x, y)
3 = (-2) × 1 + b. Let us solve for b ,the y-intercept.
3 = -2 + b.
b = 2 + 3
b = 5.
Thus, the equation would be
y = -2x + 5
