Question

A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line? Help me please

Answer 1

Explanation:

If it's a straight line the use formula

`y = mx + c`

m= gradient of line

c = y-intercept

we know that y-intercept is 4 so coordinate is

(0,4)

Equation also passes (2,10)

Use both coordinate to find gradient

m= vertical distance / horizontal distance

= (10-4) / (2-0)

= 3

y = 3x + 4
