I need help with these two geometry problems. Do not put up a link to a site. I cannot view images from others sites other than this one. (Please no sin/cos/tan)

**Find the value of each variable.**

Question 101 points)which equation in slope-intercept form represents the line that passes through (5, 1) and(-4,7)

If x=-3 is the only x-intercept of the graph of a quadratic equation, which statement best discribes the discriminant of the equation?

Use the four functions below for this question. compare and contrast these four functions using complete sentences focus on the slope and y- intercept first, and then on any additional properties of each function
