Question

Use the given conditions to write an equation for the line.

Passing through (-7,9) and parallel to the line whose equation is 5x-2y-7=0

Answer 1

y=5x+44

Explanation:

Parallel lines have equal gradients therefore the line will have a gradient =5

Substitute the gradient into the equation y= mx+c. You'll get something like this: y=5x+c

Substitute the given point into the equation. You'll get something like this: 9=5(-7)+c

Calculate the value of c. You'll get 44 as the value of c.

Then substitute the value of c into the original equation. You'll get y= 5x+44
