Question

A line on a coordinate plane passes through the point (-3,5) and has a slope of 2.When the line passes through x = 4, what is the value of y? Enter the answer in the box.

Answer 1

y = 19

Explanation:

y = mx + b, where m is the slope and b is the y intercept. We dont know the y-intercept but we now the slope and a point so we can substitute these values in the equation and solve for b.

Solving for b we will end up with b = 11.

now we have the equation y= 2x + 11

we now that x = 4 , so we plug it in.

we will end up with y = 19.

Hope this helps
