Question

On a graph you have a straight line with points (10, 70) and (25, 100) and line passes through (0, 50) on y axis and (-25, 0) write an equation shown in the graph

Answer 1

The equation for the line passing through the points (10, 70) and (25, 100) on the graph is:

y = 2x + 50

This equation can be derived by following the slope-intercept form of a linear equation where:

slope (m) = (100 - 70) / (25 - 10) = 30 / 15 = 2

Then we can find the y-intercept by using one of the points, such as (0, 50):

y = 2(0) + 50
y = 50

Therefore, the equation of the line passing through the points on the graph is y = 2x + 50.
