Is 11/20 greater than a half or less than a half

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Can someone check if i did this correct. it’s number 4 if you’re wondering.

How many solutions does the nonlinear system of equations graphed below have? a. one b. zero c. four d. two
